Campagnolo Record 8spd straight-through cassette, new in original box. 

Sprockets are 12-13-14-15-16-17-18-19. 

Bought years ago for a bike I never got round to building. 

Close ratio 'corncob' 8spd Record cassettes are rare now, especially NOS. 

Box is a bit battered from storage but cassette never fitted.
