Here is what I was referring to in my last post. The first item of insignia is a circular patch on a 1922 dated Tankers tunic. This is the first Soviet era, post-revolution Armor unit insignia. The second is found on the collar tab of a M-1925 Tanker's tunic and the final two pieces are from the 1930's thru 1940's. I do not know the exact dates of use of these items of insignia so if anyone can assist me narrow down their exact dates of use I am sure the community would greatly appreciate it!
