Indeed, that is from my old website, Salimbeti's website also has some more pictures. Some more info from the web.   The HGU-35/P integral oxygen system features a new lightweight low profile mask, an internal oxygen duct through the helmet, and an external hose with communications wires connecting to the helmet at the rear. The NADC designed mask was developed and supplied by Carleton Controls Corporation.   The "Carleton mask" is named after Carleton Controls of East Aurora, NY, a specialist manufacturer of aerospace pneumatic and oxygen systems founded in 1955. They designed the mask specifically for the HGU-35/P integrated helmet system to enable rear-duct oxygen routing. The program failed OT&E in spring 1979 and never went to production, making both the helmet and the mask exceptionally rare. Carleton is also one of the producers of the well known CRU-79/P oxygen regulator.   This PDF has some more info on the testing of the HGU-35/P in two versions (high and low pressure) also an image and info on a HGU-35/P  VTAS III with the same kind of mask: The VTAS-I II helmet assembly is a specially configured HGU -35/ P low pressure, form-fit , mold- in-place helmet assembly. The VTAS electronics and sensors are fitted into the specially contoured helmet shell as an integral part of the helmet. The reticle projector is attached to the parabolic visor as partof the helmet system.   And from a Canadian publication:  In the seventies, the USN developed a new series of helmets C HGU 33/P, HGU 34/P and HGU 35/?) attempting to utilize as few helmet shells and liner systems as possible to accommodate all Naval aviators.   And from the USN: The USN has also designed a more advanced helmet that, if successful, will replace the HGU-33/P. Designated the HGU-35/P, its major innovation Is the routing of the oxygen delivery hose through the back cf the helmet. This improves the location of the centre of gravity of the helmet, resulting in less torque about the head during exposure to gravitational forces. This helmet shell was manufactured from an epoxy based composite of Kevlar and graphite. Kevlar is a light weight, high strength material and graphite is a high stiffness fibre. The helmet is custom fit by means of a V-Tec liner. It was postulated that this helmet would cause poor seat/man separation because of the routing of the oxygen delivery hose. However, no interference was experienoed during an actual seat/man separation trial carried out at the Aerospace Engineering Test Establishment (AETE). A second major concern was the extremely high breathing resistance of the assembly. This resistance was 1.7 to 2.0 times that imposed by the A13A mask when used with the same oxygen delivery system and well beyond the recommended total resistance.   

Thank you for the help!

There are several manufacturers on FaceBook that offer to make patches of all types even the rubberized stuff. I have a board of bullion patches a military shop had on display and the owner had the patches made in the early 1990s for resale in his shop. I recall he said he had to do an order of 10 each. I also had 6-10 34th Infantry Division bullion patches that were larger blazer style patches done for WW2 34th vets and was told 30 or less were made for them early1990s.  Also spoke to a buyer for a insignia company and at that time he stated all the bullion insignia, wings and badges were sourced overseas.

Hello, I was wondering how much this helmet would be worth. It is a fixed bale front seam helmet. The heat-stamp is 270B and with last pattern chinstraps. The helmet came with a woodland camo helmet cover. It has a Vietnam liner made by Westling House with 107 stamped right above it. The sweatband is dated 88’. The helmet has been named 4 different times, with the names R.D Holt, Plamondon, V.G. Burns and Andrew H. Thank you for help.

I was wondering how deck jackets were marked up for use on the PT boats during WW2.  I read that these jacket were issued differently to those on board ships and aircraft carriers in that such jackets were accountable as ship stock and issued when working in the cold on deck and marked accordingly to working areas  of the ship. With smaller PT boats there was no room to store such clothing and individually issued for the type of working environment which PT boats were exposed too.  I was told that a patch of cloth or Disney style patch usually featuring a character on a torpedo  was on the right of the coat or similar art work was on the back of the jacket with name of crew either on front above USN logo on left or on back with hull number ie PT102 and boat squadron, not in any order but marked up on the lines inspired by the  airforce and using paint to hand either with cut stencils or by hand. Not sure if this is correct as it would be nice to see the type clothing used on PT boats not just the Pacific but in the ETO as well were it could be colder. Any reference books about on such a subject or photos.

Nope, he went to John Carroll University.  Hayden

All look WW2 era 

I agree with all the above. I collect only AAF but the line where a "grouping" becomes anything more than interesting story to only one man compared to historic value is pretty thin for me. Period engraved medals and uniform items are an example. Now, once you have a patched and painted A-2 jacket or other display items, collectors would pay a premium (historic value or not). A primarily paper lot is interesting to see the older type of paper, type print, and vintage paper clips and staples. The actual info on them tends to be fairly standard to all such papers and is available from online records, NARA, etc. I love having complete groupings (though much of my collection is not that at all) but I ask myself and also observe "What am I able to appropriately display?" and "What will people actually stop and look at?" Most people are not at all impressed at an original pay journal that the vet actually held and signed and more than a photocopy of a page. Consequently, the uniforms are displayed and appreciated and the paperwork and pic stay in folders in a closet. To a medal collector, the signed medals may be of display interest while the uniform items, pics, and documents would need to be stored elsewhere. Also, remember "historical" significance means it's just old. "Historic" significance refers to its importance in history. That's where the value part starts to bifurcate IMO. To most of us this is all very important but to an archive that has tons of similar stories and artifacts it is just more of the same "historical" items.   What original papers in a grouping say to me is this isn't a few items that has passed from person to person with some photocopies of the vet's records but rather something that has been kept complete directly from the vet or his family. That is a different grouping. Same info but different for sure. Very nice stuff. JMO, Dave

And it just keeps getting better!
