I found these rather lovely bits attached to a slightly cobwebbed Hetchins bike being stored in a wood shed.

Firstly, a wonderfully elegant little Campagnolo Gran Sport front dérailleur and secondly a high flange reversible alloy hub, with a six-speed casette on one side and fixed singlespeed racing setup on the other.
