quickdtoo,
Was the combo Huntsman (.243 & .50Black Powder) SB2 frame marked differently from the regular .50 cal BP Huntsman frame?
The reason that I'm asking is because in Brian56's quote, he stated: "CW, you are correct, if the Huntsman has been registered with form #4473 with the BATF. What I was saying is that with out the #4473 form, we can only fit muzzle loader barrels to a Huntsman frame. The Huntsman is not a legal firearm unless it is registered with the BATF. So anyone sending in a Huntsman frame for other than muzzle loader barrels must also send a copy of their BATF registration or we will refuse to install other barrels for legal reasons."
Aren't all Huntsman .50 cal BP guns made after the 70's (AL series serial numbers), "legal firearms", which require form #4473? I thought I had it down pat, but now I think I'm thoroughly confused.
OSR,
I don't have one of the SB2 Huntsman Combos, but I have handled several. There were 3 different Huntsman Combos, all blued. There were 2 different SB1 combos, and 1 SB2 combo. The SB1 combos had either a plain 12 ga barrel, or the Tracker II 12 ga barrel along with the .50 cal muzzleloader barrel. The SB2 combo had a .243 barrel and a .50 cal muzzleloader barrel. They look just like a blued SB1 Huntsman, with the color case hardened receiver and walnut stained hardwood stock. If you know how to tell the difference between a SB1 and SB2 frame, you can find out that way.
All the late .50 caliber Huntsman muzzleloaders are 4473 firearms, were not made before 2001, and can have other barrels fitted to them. The SB1 frames would be limited to shotgun/muzzleloader barrels, and up to REM, possibly some of the pistol caliber/low pressure rifle barrels. They do put the .357 and .44 barrels on SB1 frames. The SB2 frame could be fitted with any barrel, but it doesn't mean that REM would do it. The .45/.58/12 ga Huntsmans were made back in the 70's, and were not 4473 firearms, they have a large flat firing pin, and H&R would not fit other barrels to them.
Personally, I think most of this is above big green's comprehension level. I'll leave it at that.
