Thanks Larry
A real back water unit then.
With the full wording I could locate it on the net and also in Freeman's third volume about the 8th AF. He calls them Gunnery and Tow Target flights G&TT Flt. If I had not been in such a hurry I would most probably have spotted them...
Well we can disconnect 4th GTTF from 1459 FLT, since the 4th was formed on Dec 3rd 1943....
Sorry about the long shot, but I learned something from it anyway
Cheers
