I have the exact same NOS thing, including barely used 6 speed 13-18 freewheel. Includes rare instruction booklet, too. I would also like to sell mine. Nice original wooden box in slightly scratched, but otherwise excellent condition. Needs new inside cover pad, which I can fabricate for you, no charge.
Only problem - no Campagnolo chainwhips. Any standard chainwhip will do fine.
I'll do it for $575 obo
