Thanks for the steel ID Hubbub. So with Ishiwata 022 it places these frames in the mid 80's? I always find the "odd man out", Bibliobob has Nuovo Record, yours has a full Shimano 600 and mine has Suntour Sprint
I figured I would assemble it as I got it and ride it. Later, if I just can't leave well enough alone, I can pick up 600 F&R derailleurs to match the DT shifters and a 600 crank.
