I'm wondering if anyone has any info on a s&w 38 special ctg model 10-5 The serial # is d21514. Can anyone help me date this gun or give me an estimate on what its worth? It has wood grips with a checkered pattern. Its very clean. I'm not a pro, but if I had to guess, I'd say the gun is about 98%. I'd like to sell but I think a dealer would lowball me. Any help- suggestions would be appreciated. Thanks.
