It could be the case that the 77 FT is rarer than the FTS as people wanted the all singing and dancing FTS, myself included. July 1987 I visited Airmasters, travelled on national express to Luton to be measured for my FTS. I remember going up the stairs and gazing at a least 15 stock blanks and John saying which one do you like? That one there with the nice grain please Mr Welham. Stock only as the action was a venom 77 lazaglide with Mach 1 trigger. I wanted the best of both worlds and this combo had it. Still got the tshirt they did.Mach 1.5
