I picked this one up today. An I frame chambered in 22 LR. Looks to be a 22/32. The grips are not original. The serial number is 517657, appearing on the forestrap and cylinder. The chambers are not recessed. The catalogue suggests it to be pre 1935. Any thoughts on that and what the value might be? Timing and lock up are good. The pull on S/A is very light. Thanks for the input.
