No the title is not a typo :)
I'm aware that F.T.R. is Factory Thorough Repair but have come across references to No 4's being dispatched as F.T.F. as well as F.T.R. in the 60's
I'm not saying they were stamped F.T.F. but are logged as F.T.F. can someone give a definitive answer as to what F.T.F. stands for please ? (without guessing !)
Many thanks Kevin
