i recently got a nishiki track frame with a serial T3 0010 any idea when it might have been manufactured? the shimano BB cups are stamped ZJ which is OCT 75 so i suppose its around that time, attached are a couple of images of the frame as it is atm, sorry for non-driveside its just how i had it in my stand to repack the BB
