I ran across an old K-frame post-victory model. It's a 4" .38 special. The serial number is S848xxx. Finish is shot (no rust,) but mechanically sound. The grips on it fit, and are for a K-frame, but are totally wrong (too modern.) I've heard that the S prefix puts it between 1946 and 1948. I also understand that this is not a Pre-model 10 because it is not '49-'57. All serial numbers match except for a weird "B7" stamped under the cylinder crane on the frame. The hammer seems to fall into the pre-war style but surprisingly blocks the rear sight before it is cocked single or double action. If you guys could provide some insight into this one I would appreciate it.
