The source of this photo thinks it is related to the 449th Bomb Group. Based on the lettering under the "449", I'm not sure that is the case. Can anyone provide an explanation for lettering? Thanks.
TH/C does not appear in any Army abbreviations I am aware of? However, M.M. Bn. would be Medium Maintenance Battalion, which if the photo is post World War II would be unusual, since that was not an official designation after 1942, when responsibility for all maintenance was vested in the Ordnance Department (prior to then vehicle maintenance was the responsibility of the Quartermaster Corps). I can find no evidence of a 449th Ordnance Battalion organized in World War II and typically World War II units after 1942 would be companies as the integral battalions were broken up (the exceptions being Ordnance Base Maintenance Battalions and the Ordnance Base Automotive Battalions, which were numbered in the 100's and 600's). That being said, it is almost certainly a photo from the late 40's or early 50's.
A wrinkle. If you look to the right of that, on the corner of the table cloth, you see another wrinkle shaped very like the dark one.
The photo spooks call it a "box impression", meaning the photo was left in a box with other stuff. I once saw a stack of boxes full of photos. The boxes had mostly caved, threatening a landslide of pictures I wasn't cleared to see.
MM could also be "munitions maintenance" which is what our ammo squadron was called: 7th MMS. Perhaps it was still referred to as a "battalion" due to USAAF still being Army? That said, I looked up the 449th, and their website doesn't feature this pic that I found. It appears to be a post-war reunion pic.
It has to be post-war, civvy clothing and wives drinking around a table. Still unable to identify the unit.
Thanks to all for the replies. The photo was found by someone renovating a house and sent to me. I figured 'Bn' was battalion, but had no clue as to the other inscriptions. Did not seem related to the 449th Bomb Group as the sender thought.
