I picked this revolver up at a local gun show this weekend.I am looking for information about this model.After looking in the S.C.of S&W it stated that there were around 14 of these made,with the serial number prefix of BRF.What would be the value of this revolver?It did not have the box or papers.It has some bluing wear on the muzzle,there are a few dings in the cylinder from somebody dry firing it,but there does not appear to be any rust,pitting or boogered screws.The action is very tight with no endshake.Any info would be appreciated.Thank's
