The more desirable ones are the Model 27-2 and earlier based upon the pinned barrel, recessed cylinders and the three "T's", and even the target stocks. A variety of barrel lengths with varying length desirability.

The long barrel (8 & 3/8") may not be as desirable, but I love it for all in beauty of the checkered top strap and bluing.

I would have to go along with 22hipower's thoughts as to value of the OP mentioned revolver.

Based upon the stocks alone, they could be worth $150.00.
