Yes, it is Book 1. It is a paperback book with 85 pages. You can find them on eBay from time to time for a reasonable price.    

Produced in WW2, yes, hiwcer not technically a WW2 paratrooper helmet. Coming with a P55 liner, we would say this is "post war configuration".    And then there's the whole debate of where M1Cs were actually used operationally in WW2.    Still a neat helmet. 

Yes, that's a legit P55 liner. 

Chincups get kind of crazy and do so quickly. There's a thread on here about them.    To the best pf my memory, they stopped stamping "U.S." on them around 1963.    The two keys to whether they're late 40s/early 50s is thread material and stitch width. Thr earley chincups used natural material for stitching, like cotton. Later ones used nylon. Also, big thick stitching is an indicator of earleir chincups. Thin tight stitching is something you typically see in newer ones.    There's other things to look for but the chincup thread has those listed out.   

This WW2 M1C shell (heat stamp 1179D) came with a 50's infantry liner and 70's ERDL cover...... got it for a steal as well

I just wanted to get some feedback from the brains trust on if this helmet  and if is a legit factory made liner...   Its a 1962 Firestone jump linere with the remnants of two decals 172nd infantry brigade (which is upside down!!) and 23rd infantry regiment which align for the 1963 time frame.   not sure about the nape strap either   Picures attcahed.

I've just picked up another chin cup and noted that there a couple of differmnces between the two I have. two differnt shades of green. the stitching joining the end of the cups are on oposit sides.  see pics.   Have any of you seen this before?      

Hi Siamundo   Here is a white Maltese cross 17th Inf, image is from a good friends collection.   There is a possible suggestion that the colours Red, White and Blue(?),might be related to the battalion colours,again that is only a sugestion.   Anyway thanks for posting   Phill            

Although they did look it in my initial photos, none of tgese badges are subdued. The CMB especially, just has a deep, uniform tarnish. All the badges are just tarnished silver.
