I really dont unfortunately... there are little to no markings on this thing. Seems a little cray that someone would make a packing type rifle at this point, but with respect I am an amature and not doubting your judgement. Says Spain on it
Spain is where many black powder reproductions are made. I think the reproductions started being made in mass quantities during the 70's and are still being made by numerous companies. it's a big market and lots of people buy, shoot even hunt with them. Most are inexpensive(under $500) and many are in the $200-300 range new. It's much more feasible to spend a little money on a rifle or pistol to shoot than spending a thousand or many thousands to shoot an original and risk damaging it.
I think I had the twin to this one in the 70's. Two piece stock, hardest piece of wood I've ever encountered on a gunstock.
IIRC mine had rifling that looked like it was done by rabid beavers. The triggerguard and buttplate looked sandcast.
Looks like this one got inletted and assembled to the point where it was usable, but the final sanding and finishing of metal and
stock never happened.
