Wonder if someone has one for sale.
A few Uberti replicas on Gunbroker:

But if you looking for an original, those are BIG bucks.
USA made, although many Italian clones from Uberti etc are pretty good.

.44 Rimfire is basically unobtanium today, it was last produced commercially in the 1920s or 1930s. Even single rounds are collectable. I recall reading about a Sioux or somebody who has a Henry and an ever dwindling cache of ammunition that has been handed down from father to son, father to son, from whomever captured it originally. Once every year or so they pop off a couple rounds or somesuch. Original Henry repeaters are expensive.
But there are some really well-made replicas out there by Uberti of Italy and Cimarron and others that are authentic, accurate and come in much more available calibers - like .45 Colt and .44-40.
Real fun gun to shoot!
