1971 Campagnolo Gran Turismo Derailleur

I bought this Campagnolo Gran Turismo derailleur as the start of a vintage bicycele parts collection. The Gran Turismo was introduced in 1971 and was on the lower price and quality end of the Campagnolo derailleur line. It had a super wide gearing range, and looks more like a Ninja weapon than a bicycle part. Heavy too - all steel construction without any efforts on weight savings. I dissassembled it and shined it up a bit. Looks nice sitting in my display case :)
