I just received this original photo. It's very tiny - only about 2" across. What Unit ???

I think that may prove to be impossible to tell..however the period is the early 30's..

Thanks anyway - It's weird how it looks like a bullion tab, it's so bright. Probably not, but it looks that way. I'll post the whole picture later. He strikes quite a pose - and with an attitude.
