Thank you for submitting your item for appraisal. From what I can recognize on the photos you provided it appears to be a Smith & Wesson 32-20 Hand Ejector model. Very nice are the mother of pearl or lucite grips. Unfortunately the nickel plating is peeling off and there is some rust . The estimate is based on similar actually sold at auction. There is no measurement for the sentimental value you might attach to the item.
