Hi, I have this old .38 that was gave to me a few years back. Not sure of age or model as a model number don't seem to be there. It was improperly stored in an old military flap holster that had drawn moisture and caused surface rust, the worst being under the grips. Thinking of sending it to Fords to be blued & cleaned to hopefully what it looked like when my Grandfather purchased it long ago . I would love to know model & approximate age. Thanks !
