First- incredible knowledge on this site! I’m hoping someone can help. I’ve had a nice A-2 in my collection for years- the family removed the name tag, squadron or group patch, and I believe a shoulder patch that had been sewn over the left shoulder decal. They left the ‘Major’ tank shoulder insignia. No other paint, and no internal owner markings, and I have no leads on a name or unit, but patch outline was unusual, so I kept looking. I believe it most closely resembles the 100th Bomber Group Emblem IF the ‘extra’ material is removed from the border of a typical round patch, but I welcome any and all opinions. There are some thread remnants at the patch area and there does seem to be some glue or paint residue in the center of the patch area - does this make it more likely a leather, or canvas, or cloth, or other patch? My hope is to someday narrow it down to the original owner, but my best chance at this point would seem to be to ID the patch and unit first. BTW, I’ve already spent a lot of time on the 100thBG site. Help! Thanks, Jim
