Compromises made in conditions of convenience of availability or opportunity, of course can offset long waits for something which may never come.
I have been looking for one of these, and, I am still looking...
This sounds a little high to me, given your description...and with a non matching Cylinder, or any other changes from 'Original' configuration, were you ever to offer it for sale later, chances are, that would discourage any informed prospctive buyers...or disappoint an uninformed one, if he or she later became informed.
Very nice ones, with no faults to find other than slight wear to the Blueing or a little light freckeling, do seem to be offered for about that same price occasionally, or a few hundred more as small percentages of Blueing loss, get smaller.
Seems like there are quite a few really worn and doggy ones, modified ones also, usually being offered for five or six, and appearently selling at that over a long enough period of being offered, where, for me, I would rather find a pretty darned nice one, unmessed with, with low use, and merely some Holster Wear, and spend eight-ish ( hence, I am still waiting ).
Blueing percentage is almost always less, maybe much less, than non-experts tend to think.
Original unrefinished Stocks would be smooth, lightly reddish Brown Walnut, and no Medallian...and the Revolver when retaining it's original configuration, would have a Lanyard Loop swivel on the Butt, and, the Military Number and Model No. stamped on the Butt also.
Serial Number generally will be found on the small flat under the Barrel by the Frame, where the Ejection Rod sits at rest, and, on the rear Cylinder Ring.
I do not remember right now, if the Numerals on the Butt are always the same as the Serial Number, or, were a Military Number assigned to the Revolver, but, this would be easy to check, if all three ( or at least if it, and one or two of the other locations of the Serial Number,) agree.
