Picked up a Nishiki Freewheeler recently, complete with the much derided FFS. From perusing this thread, I believe it is a Giant built 1985.
Drive side dropout G0485
NDS dropout
Also the BB is stamped 68E, which I guess denotes BB width and threading? I have not measured it yet.
Decent overall condition although coated in a thick layer of grime. The rack has already been removed since I took this picture.
