  1. Looks like it was painted for a "Tank Girl" cosplay costume
  2. Here is a snippet from a letter written by McCord Radiator and Manufacturing Company summing up their helmet related participation in the war effort dated 1946
  3. I see this is an old post but here is a link in the event you were not able to find an answer somewhere else https://cdn.shopify.com/s/files/1/1065/6146/files/MC_H_Vol_70_No3_M1_Helmet_Lot_Nos.pdf?3737742651470471381
  4. I am not able to comment on design changes regarding alterations to the M1 helmet's requirements due to the need for better concealment or ballistic increase as I have not read anything relating to this. If there is any potential study into the depth of the helmets draw specific to ballistics I would imagine that would be found in the studies and experimentation done in the late 1960s into the 1970s helmet program. The first steel helmet bodies pressed at a more shallow draw or "lower profile" from that of the first helmet bodies pressed by McCord were manufactured at Schlueter Manufactu
  5. I am afraid I lack the capacity to understand the need for attempting to date a helmet shell to the speculated year and month of pressing. But then I am old and crotchety so...... As to your description of the component parts of the steel body (rear seam edging, hinged chin strap loops with OD#7 straps) your helmet exhibits final manufacturing characteristics which would have been implemented during 1945 manufacturing. Any liner would be appropriate however, if you want a liner with late war manufactured characteristics like your steel shell, I suggest a high pressure liner with blackened
  6. The M-1 Helmet: A History of the U.S. M-1 Helmet in World War II by Mark A. Reynosa Mark performed the first in depth research into the subject. This book is the most comprehensive and provides solid references to its topics. If Mark's books have a down side to them it is because Mark is an Engineer and his writing style is that of an Engineer and that the pictures were not high end studio shot. Helmet books on the M1 that follow this publication may have some new information and far better photographs but I guarantee all of them lean heavily on Mark's first book as a foundation refe
  7. They are not uncommon but are somewhat difficult to find in unused condition. The double mark indicates a liner made in the 1950s by CAPAC manufacturing Co. The 5 & 1 indicate that CAPAC leased a helmet liner mold from the government, originally used by Westinghouse in WWII, and modified the mold by adding the CAPAC logo in 1951. Westinghouse is the other contractor at this time but they didn't modify the molds they received from the government instead they added a white Micarta ID tag to their liners.
  8. Normally liners like this were determined defective at the manufacturer. They were then webbed with available materials and sold as toys, work bump helmets or to VFW to use in parades. They use plastic, compressed paper, various fabric webbing and the like to make a quick suspension. I have seen several examples that do not put in neck support webbing as it is not needed when the liner is not intended to be worn with a steel helmet.
  9. As referenced by Doyler, The style cover you posted was used by the Marine Corps in WWII The Army experimented with a cover of significantly more complex design and construction. These covers in conjunction with uniforms of the same patterns were attributed with friendly fire incidents due to confusion between fellow U.S. soldiers wearing these uniforms and the camouflage used by the Germans.
  10. If memory serves, Westinghouse Mircarta Division supplied all the resin impregnated duck cloth for liner manufacture during the 1950s. A separate division of Westinghouse, Mine Safety Appliance and CAPAC were the three manufacturers that actually pressed liners during this time. Westinghouse and MSA, in addition to their respective mold in marks, chose to include a little white dated cotton tag with the Micarta Westinghouse logo to acknowledge Micarta's supply of the duck cloth while CAPAC chose instead to add the Westinghouse logo to their mold in mark along with the date the mold was made at
  11. Let me guess.....your liner was made by Firestone. The webbing kits in many of these last production run (which will have mold in marks for Firestone or Firestone over Inland) were made too small for the liners. The excess tension in the webbing cause the metal eyelets installed in the webbing to shear the brass rivets behind the A washers at the rear attachment of the cradle.
  12. Can a leather chin strap from a helmet liner, that is already brittle and dry be restored? The short answer to this question is no, there is nothing that can be done to preserve and soften dry rotted leather. Unfortunately, once leather has reached the beginning stages of dry rot there is nothing that can be done to reverse it. There are a multitude of products made for leather treatment and they work for their intended purpose on boots and saddles and the like when the leather is in good shape and used regularly. These same products will not revitalize dry stiff leather and generally qui
  13. RichRaider, Very nice helmet!! Unlike the Army in Europe, who chose to deal with the reality/myth of blast force on a clasped helmet causing head or neck injury by securing the strap behind the helmet, the USMC often wore the chinstrap loosely clasped under the chin during landings. After the issue of the T-1, it is not uncommon to see M1 helmets of early, mid or late war manufacture fitted with the quick release system in the pacific. Unfortunately, all the component parts of this helmet are typical to WWII on through early 1950s issue so dating it specifically to WWII is not possible
  14. Came across this picture and thought of this post. Picture caption describes a soldier in New Guinea who had (the box pictured below his rifle) air dropped onto his helmet
  15. Here you go. Front seam hinged chinstrap loops, OD#7 straps with OD#3 stitching (note: hinged loops appear to be replacement over broken fixed loops)
  16. I do not recall ever having seen a letter "O" suffix even on post war helmet shells. I do have a letter "N" of WWII period manufacture which is at least close enough to assume a "O" suffix is at least possible. By obseration the font case used for the letter "C" suffix by McCord looks like the number zero "0" with a cut out to the right making it a letter "C". Following this logic would lead one to assume the letter "O", if in fact it does exist, would likely be the same in appearance as the number zero.
  17. Ran across this picture and it reminded me of this post. Thought I would add it to the thread since it appears to be a similar treatment of netting.
  18. Looks like a BF McDonald construction helmet liner has been added to the liner suspension
  19. Thanks for that one! Looking at the liner, wouldn't 1.25" deformation put it in your dome anyways? Apparently yes you are correct, it looks like they calculated the position of your head within the liner based on how the suspension cradle was supposed to be adjusted to prevent serious injury. If the liner cracked, splintered or flexed upon the impact test down to the 1 1/4" limit it was rejected.
  20. I was reading this rather interesting (if blurry) test on M1 helmets and how well they could hold up to .45 caliber rounds: http://oai.dtic.mil/oai/oai?verb=getRecord&metadataPrefix=html&identifier=ADA954941 (Strange test, since basically never was a US troop getting shot by a .45 but OK) The test was not set up to measure the affect of a .45 caliber round against the armor defense of the helmet. The ballistics test was established to discern if a helmet could adequately deflect an impact from a projectile originating from a specified distance traveling at a velocity of 725 ft
  21. Nam Steel was never in print, to my knowledge, it was only sold as a PDF file on CD as I recall. Post-World War II M-1 Helmets By: Mark Reynosa has some of the information you are after.
  22. It has been a long time since I have read over materials dealing with the 1950s helmet manufacture and I can't remember where I tucked my book away but if memory serves, Westinghouse Micarta Division supplied all the resin impregnated duck cloth for liner manufacture during this time. A separate division of Westinghouse, Mine Safety Appliance and CAPAC were the three manufacturers that actually pressed liners. If I recall Westinghouse and MSA, in addition to their respective mold in marks, chose to include a little dated white tag with the Micarta Westinghouse logo to acknowledge Micarta's sup
  23. It is the 1934-36 version of the liner. Two variants exist: One version where all attachments are rivets and a latter one which still has rivets on the hook release strap but both straps are box stitched to the liner frame. This liner was issued as an upgrade kit for the M1917. After the WWI liner was removed from the helmet and this liner assembly was installed, the helmet became the M-1917A1. The chinstraps were integrated into the liner assembly and were not attached directly to the steel helmet itself. The straps were thread through the existing loops of the helmet body to add stability.
