H&R PREMER SECOND MODEL SMALL FRAME TOP BREAK R.F. & C.F. ----------1905-1941
Small fame double action top break revolver with double top post barrel latch; calibers and cylinder capacity, 22 rimfire-7 rounds, 32 S&W, 5 rounds; automatic cylinder stop; standard finish Nickel with case harden hammer and barrel latch; standard barrel length 3 inches, with 2, 4, 5 and 6 inches available as optional.
It's basically the same as the Premier edition only it's
unmarked. This was apparently a common practice as H&R sold its revolvers through various agencies and outlets and could be sold as a 'second model top break'.
Another source suggests that patent dates 5-14-89, 4-2-95, 4-7-96 were listed on 1905manufactured guns only.
In that condition you are talking about a $75-$100 pistol, I've seen one with near immaculate shiny nickel that sold for just under $200. And it looks like it is NOT pre-99.
Carefully look over the left side of the barrel for a caliber marking--all H&R references say it should be there, this could have been re-nickled and therefore buffed out.
I found pretty much the exact same revolver at
