During WWII and the Korean War, Corps of Engineers troops were equipped with quite radioactive lensatic compasses. I usually see them with a black paint, but sometimes I see golden and dark green paints. The radium lume inside is most of the time yellow (ZnS:Mn), but can be green. The reason these compasses are so much more radioactive than other radium painted models is because of the "backlight" in the bezel. On the back of the bezel, there is a large strip of hot radium paint. This strip basically illuminated the whole dial, allowing troops to easily read the numbers inside. That giant strip is usually on average ~20 microcuries (around 20 micrograms) of Radium-226, which is a really decent amount of radium to put in a compass. Most aircraft gauges didn't even use that much radium. They are safe to handle for a bit, but don't keep them in your pocket or sleep with them. The other big hazard with these compasses is they have exposed radium paint on them. On the azimuth, the two dots have a tiny splotch of exposed radium lume. After 70-80 years, the binder in the radium lume has degraded severely and it can easily flake off. Radium-226 poses severe internal hazards as it is primarily an alpha emitting isotope. Every time I get one of these compasses, I carefully apply a small amount of clearcoat on the azimuth to prevent radium contamination. The green M1950 compasses also feature these very radioactive backlight bezels. I have a few coming in the mail that I'll make a post on when they arrive. -

This one and the one in the link from IMA look very similar except for I noticed the one I'm inquiring about has what looks like a brass outer part and the inside is probably silver unless the outer part was clad with brass... Unlike the one from ima that looks all silver... thanks -

Recently saw this patch on a uniform on eBay, has anyone been able to ID it? Or is the consensus still that it’s a novelty patch? -

Nice collection. You got there. Looks like it took some time put together..... As far as markings on the back, one of them are marked G.A. EFRON SILVER STERLING..... And it looks like the ship he was on was uss the Blackhawk. I did a little bit of research on the history of that ship and it seems as if it served its life doing mind sweeping patrols and them was refitted with torpedoes later on...thanks -

I have a Bombardier wing like this one, but mine does not have the sloped off edge of the Observer circle, and mine also does not have the ridge across the back of the wing on the one side like this one. In looking at your photos again, I also noticed your wing has an extra bulge on the bottom edge of the Observer circle. I feel like most Amcraft pattern Bombardier wings were made using a wing with a target background not the Observer background, and I don't know that I have ever seen an Amcraft Observer wing made with this forcer. I'm not sure why they would have made Observer wings post WWII to use as the base wing for Bombardier wings. -

No maker mark on the holster. Clearly made for an M1911. I have no idea who Jean Jones was. -

So there are some big maps there 45 by 24 or so the big yellow and red ones. I am thinking of taking the whole manual apart and selling it piece by piece. Can someone please give me advise or direct me where I can get some advise.
