Wow, what an awesome grouping.  Love everything about it.  Thank you for sharing that post here.  I appreciate it!

We have this turret punch in the shop where I work. US marked in several places and unit marked to the 336th Aviation Co, It still works fine!

It's from the AN/TRC-2 radio TM from April 1944.

Thanks so much for all that... I just recently learned we'd sent USSR some of our Jeeps at one point or another (from the new Tom Hanks WWII television series) when they needed some help back when. I wonder if any of them are still rolling along in Ivan's care...

SWEET!!!! Great score! Finding out whose it is would be icing on the cake. I hope it is eventually ID'ed. 

Uniform Change 15 apparently covered the hats for the Yeomen. https://www.history.navy.mil/research/library/online-reading-room/title-list-alphabetically/w/womens-uniform-1918.html   HATS 267. To be straight-brimmed sailors, of navy-blue felt or white rough flat straw, shaped to conform to following dimensions: Brim 2-3/4" from crown to outer edge. Crown to be 3-3/4" high, 6 1/4" wide at top and 6-3/4" at bottom, 7-3/4" long at top and 8 1/4" at bottom. To be ordered to fit head size of person wearing it.     Except for the chin strap (that wasn’t actually required by regulations, apparently), the dimensions would have been in conformity with the M1866 USN Officer’s Straw Hat, further verification that it truly had settled into a standard form by then. 

I realize how it could appear that way. However, there is a stamp with the last four of the service number in the trunk and that number is stamped inside each piece of apparel in the trunk. As for the other items though, I guess there isn’t anything that proves their connection. 

Got this off of Ebay for $125 just missing the visor assembly but that will be replaced by the SPH-4 double visor assembly so no problem there as Army SPH-4's (Excluding the SPH-4B) were upgraded with those anyways. Also missing is the complete drop cord ear seals earphone elements boom mic swivel parts (I have the parts needed anyways) and boom mic assembly. Helmet is extra large and comes with original impact liner and I put in a size large HGU-56 TPL assembly and it fits quite well. I do have some NOS in original package mic assembly and cables and NOS earphone elements H-347/AIC. just need to buy the drop cord ear seals and the boom mic frame and thumb screw.

I thought I might be able to get an I.D. from the guy I purchased it from, but he says he can't find the paperwork he had with it. Its definitely not fake, very well made and I paid $5 for it.   Thanks for the help! 

This would have been the "normal" collar insignia of an enlisted man in the new US Army Air Corps (which was not created until 1926). It was the winged propeller on a flat disk.  The second photo shows the checkered (or hatched) version of the disk, with a rim around the edge.           This is a photo of an enlisted man in Hawaii wearing the Army Air Corps collar disc in the late 1920s.  Credit to Salvage Sailor, who posted it in a US Militaria Forum about the Pineapple Army DUI of the Hawaiian Division before WWII.
