It appears to be an old but standard quarter-inch ID fitting. Could have come from just about anywhere ... except a U boat with metric fittings. Sorry, but it seems pretty unlikely.
EDIT: And Lunkenheimer is based in Cincinnati, OH. Admittedly, that town's chock full of Germans ... who've all been Americans for 250 years like my family.
I'd have to guess the uncle pulled a fast one.
Thanks. The 1/4 is a dead give away that it is NOT from Europe, otherwise it would have been in metric.
It probably did come from a US warship though from WW2, or at least a parts bin!!

Having crawled around the USS Texas and USS Lexington with my boys four times in the last three years, I can verify that there's about a zillion places onboard that valve may have been in use ...
I wouldn't put it back in use, however. WWII-era fittings leaked.
