This is a Virginia Dragoon revolver, an engraved one, made by Interarms, it's a copy of the classic Colt 1873, though stronger, built for .44 Magnum
Interarms, back when they existed, were mostly known for importing firearms, milsurp, foreign commercial guns, antiques, you name it, but they did actually produce some of their own, and this is one of them. They can be easily distinguished from the typical Single Action Army for the slightly taller frame and the fluting running horizontally along it.
There are some ideas out there about the Virginia Dragoon that it's unsafe, which to my knowledge isn't true at all, and there's the idea that they aren't accurate, which actually has some merit.
In the beginnings of production, barrels weren't made properly, and some of them had oversized bores, which obviously isn't a good thing, particularly given that the .44 Magnum cartridge actually uses 0.429 inch projectiles, which are supposed to be swaged down a little by a bore that is slightly tighter than that. In some examples, this could be so bad that if you dropped a loose .429 caliber projectile down the barrel, it would just rattle down there and come out the other side.
If you're looking to buy one, consider making sure that the bore is actually correct, as with the sloppy oversized ones, you will loose shitloads of energy and get basically no spin-stabilization, meaning it won't shoot straight and will be all wimpy, which .44 Magnum should never be.
This problem was solved early on though, and most of these revolvers have perfectly fine bores.
