[QUOTE=Bellarine;1991460]Found this in a box of Gipsy Major parts and thought nothing of it until I spotted the FB part number on the main shaft. Anyone able to ID what it is or what it was used for?
Cheers

Cant help but i am interested in the Gipsy parts comment. I’m in NZ with a J5F Auster project with a Gipsy Major. Any Ali heads lying around you? 😀
