I have a well-loved but still snazzy Nishiki Pro frame/fork/headset/d-o adjusters/seat-tube clamp-bolt/seatpost for sale, original paint, chrome, one faint graphic on the seat-tube, and a nice headbadge, as shown here:

$250 shipped in the lower 48, or make me an offer.
58cm c-t seat.
57.5 c-c top
these were always nice, easy-riding bikes. english threaded. With eyes for fenders or racks or what-have-you. There's also a stop on the underside of the tube for a bar-end cable-guide or d-t shifters. a nice touch. Or this would make an interesting fixed-gear road bike.
All-japanese stuff from the 70s would be appropriate for a build. Easy parts to find, and cheap too, esp. on a donor bike.
E-mail me if you'd like to buy it.
