Prewar US MK2 with foreign modern pressure switch. They originally would not be used together.

what would it be worth, The friend wanted to know what I would pay for it??

With just the one photo to go off, its rough condition, not sure if the bottom has the plug or not, nor if the fuze well threads are still good, looks like they put a sleeve to get the  modern pressure switch to thread. Its a mismatched piece in rough condition with unknowns, personally I wouldn't pay over $65 for it. Its nothing special nor rare either, not trying to hate but that's the reality of it.
