Help With Part ID Please

Hi Everyone

I have been given the challenge of selling off a stack of surplus items from the Australian National Aviation Museum. There is a heap of stuff that has to be sold on to make way for a new display area, so bits from Beaufighters to Jumo engine parts are going….

That said, I usually am able to ID stuff really quickly. But this unit has me totally stumped (and the rest of the crew as well)

It seems to be an emergency chassis lever in case of electrical failure. part number on base is 80285 12 B O HV2

Any ideas? I found it next to the Wessex parts but doesn’t look like it is…..

Cheers
