Hello all,
I own a mint uniform of a WWII colonel of Engineer Corps. (I'll put a photo in "Uniforms" forum asap).
On the left shoulder is a patch of Army Service Forces, on the right shoulder is a patch of South Atlantic Command.
Could you help me to list matching Engineer Units, from 1943-1944 era, according to both patches?
I would like to purchase two distinctive unit insignias to complete it and I don't want to commit a mistake.
PS: I try to do my best in English, please be patient if horrible 
Would love to see the photo. You can add it to this post. We will try and help you out. I have all (or almost all) of the engineer insignia for every unit.
J'aimerais voir la photo. Vous pouvez l'ajouter à cette poste. Nous essaierons de vous aider. J'ai tout (ou presque tout) de l'insigne d'ingénieur pour chaque unité. Excuse my French!
