Aviation Jersey were in the 1970's Alvis Fighting vehicle main dealer. They had a workshop at St Aubin's in Jersey, and also built electric wheelchairs. I never decided wether it was cashing in both ends or salving the conciense. The place was quite unremakable from the outside but was able to fully rebuild Meteor engines. They also did as the name suggests aviation work, but I was never involved in that. I did work for them for a short time back in that period. The company got grief for rebuilding South African Saracen engines. About two years afterwards some Poiltico got on their feet in Westminster and started spouting off, especially as some spares had come from MOD Aldershot. There was also allegations of illegal modifications on a Merlin engine fitted to a Mosquito that crashed. The last I saw of AJ there was a single office tucked away behind the St Peter's Co-Op, but that building has since been demolished. I see now they have moved out to Le Hoc, weird place out that end of the Rock. Though Seagrove stores is only a small ex shop building.
