Hello, This is a good source for tanker information.   http://www.big-red-one.org/M1938 TANK HELMET INFO PAGE.htm

Gone….the rank insignia  I went to another estate sale earlier…and decided to pass by to see what was left.  I picked up these items

British?

This is the third I have come across over here in the past couple of months by two different sellers, both sellers are insistent that they are real.    To me it looks like somebody has clipped the clutch back pins off and changed it to a pin back.     

Thank you Salvage Sailor. The first link doesn't seem to work though.

There were many Mexicans who were citizens.

Brilliant, thanks! A very interesting photograph. Compared to the Navy and Marines, the Army didn't offload regularly like this, otherwise the lifting rings would have been adopted as standard I guess?! Cheers

Ok, I think it may be a Patch King railway artillery reserve patch based on a search but if someone has a different idea let me know.  I don't know why it's stated as a "Patch King" patch though. https://www.usmilitariaforum.com/forums/index.php?/topic/8082-railway-artillery-reserves/

There was an interesting World War I uniform at the show that had a patch on it.  I’ve never seen anything like it before. Maybe someone else on the forum might know what it is.  It’s that patch under the big A that I don’t know what it is.

Yes, my uncertainty does regard what an earliest date could be, comproved by any references (period pictures, or something) of actual service for the A-10 (R) in overseas units. This 'cause should it turn out being a too late time, that pulls my future display beyond the acceptable timeframe in wich I can assemble the aviator without the AN-R-2 raft case attached to the AN-6510 'chute.  Date of 4-1943 as molded into the rubber of this specimen isn't an issue if anyone could comprove the A-10R was already seeing service in February-March 1943, that's not important to me. Sweeting's book cites this variant as 'standardized in late 1942', yet I cannot find any official reference prior to February 5th, 1943 when Technical Order 03-50B-1 came into effect.   If I can find out any comprovation of the A-10R being in service out there in very early 1943 I'll put it on the character, but if not the case I'll do without it   -    in fact the guy will be a P-39 pilot of 68th Fighter Squadron flying from Kukum Field at Guadalcanal and I'm guessing in most of those missions, oxygen wasn't needed.
