What gun was this for!?
Pour quelle arme était-ce!?
Tardy freres Paris
30 mm that must be probably for the big hunt
Here’s a similar one that sold a year ago: https://auctions.holtsauctioneers.com/asp/fullCatalogue.asp?salelot=A0918++++615+&refno=++128043&saletype=
That is one impressive Pinfire shotgun and the wheeled version is bigger.
I only have an 8 bore rifle I may show on this forum. German made.
