Would anyone here be interested in a late 60s/early 70s (?) TT chainset? Specialites TA - 180mm/59t single ring. British threads as per markings (W). Could 1775 be year 1975?

It's not crank length is it? 177.5mm perhaps?

TT chainset?

The "3" under the tooth count is for 3mm, i.e. ⅛" chain. I have a matching 65T NOS here if anybody is thinking about taking the cranks for their fixed TT build but worries that 59T is a bit too small 🙂
