I have a mint FT-140 which I bought new. The serial number is F750807 JAPAN I think this shows that it was manufactured in 1975 which tallies with when I bought it.
I bought it in 1976 in a Guitar shop in Station Road , Redcar , UK to the best of my recollection. I have looked after it carefully and always kept it in a case when not playing it. It had minimum playing from 1986 onwards as I had young family from then onwards and I diverted to electric guitars and then classical models, but I still like to play it now as I have more time available.
There are only a few marks on it, I think only I would know where they are they are so small.
Its not a Martin but I think its still maturing.
