Hi Nick, – It’s from Hess’ s Bf.110! :diablo::dev2:
Don

It is a 110 VDM, the 109 would be numbered 109 I have a pair somewhere and one of which was taken apart by Peter Rushen in the 1970s and he showed me the markings and explained why
The clue is there in the stamp 9-11085.

Thanks for that Trolly Aux – that would make sense – I thought there must be some info in all those numbers – and in that case perhaps Don is right! 😀
