Complete, original and unused (mint condition) A&R Cambridge C77 stylus and full fitting kit including weight and basic instructions. I purchased this in the early 1980's as a replacement for my Dual turntable but it was put in a drawer and forgotten about. This is a rare opportunity as it has never been opened apart from to take photos Note: buyer pays postage
