A couple of things first as I've had an opportunity to dig a bit. I had made the assumption (remember assumption is the antithesis of exactitude) that the example had been imported into the U.S. of A. But this would not be correct seeing Prussia is spelled like it would be in or near Russia. So it was a Russian or neighbouring Russia client. Typically one would see Borussia and many times less Porussia and possibly Jani or Clay can confirm the Slavic variant Porussia. Funk had the export business so his contract mechanics would have known the proper terms to be applied. So it is possible the example was a War trophy of sorts but I'd guess it odd that such a bore for the region. Anyway a long shot wold be that it was destined for the Russian region and was used to fill an order to the U.S. of A. I suppose you haven't any history on it?

Albert Valentine Paubel & Frederica Funk were born in the very early 1800s and were married by say the 1830s. They seem to be the relatives of C. Paubel & I'd guess C. Paubel to be more the grandson of that line instead of marrying into the Funk family as his line was already married into the Funk family.

Last, I'd hazard a guess the scrip WS(if that is what it is near the forend hanger) is for Walter Schilling, that is if he was old enough.

Kind Regards,
