It seems to be all nonsynthetic threads and doesn't  glow. If that helps any.

I don’t think so, but I will check this evening. You’re talking about where one would find the B/N marking on a BMCO M8 or M8A1?

This is the complete grouping of Frank L. Ingram. He served on the Enterprise, Yorktown, Wasp, Hornet, and Intrepid and more. He was a first class aviation radioman. He fought in many famous battles such as Truk, Roi-Namur, Makin Island, and other various Palau and Mariana islands as well as many many more. He was involved in multiple reported crashes, but the only logged one was on the Montery on 6/16/45 where he had a plethora of injuries including a collapsed lung. According to the family he gained 5 kill notches on his sidearm from one of his previous crashes behind enemy lines. At the end of his career he was awarded the Asiatic Pacific with 5 stars, among many other awards. The only original medal left is his good conduct medal which is named. The rest are re-issues in 2003 which I have the original paperwork for. He was awarded the Air Medal but when the family ordered the particular supplier was out of stock. The flight jacket and uniforms are all named which is always a bonus. The most interesting part of this grouping for me at least has to be the kill notches on his S&W USN Victory Model. Out of all the groups I own this is probably my favorite. Enjoy!

Is there a heat lot number on the underside of the guard?

Here's correct markings for a reconditioned Kinfolks with the plastic handles.    

Very nice one. I have one missing dice 

They are good!

Found this last week. There is a pair of dice that goes with it. But they were gone. Supposed  to be money in his left hand. Couldn't  pass it up for 5 bucks.

The E6-3-7 Army Assault Gasmask began development in 1943 and finalized in early 1944. It replaced many of the army Lightweight masks like the M4-10A1-6 Gasmask on the right.  Major improvements included a waterproof carrier, an attached filter canister, and smaller filter canister. Early prototypes of the Army Assault Mask featured a metal horn that was mounted to the facepiece and the headharness rivet with 40 mm filter port, other modifications were made to the older M3 Army Diaphragm gasmask and later models such as the E19 Featherweight mask were produced as well but never entered mass production as they were much more complicated to produce. Towards the end of the E6 project it began to look closer to the Iconic E6/M5 we see today
