Hello fellow members...I'm trying to find out a bit about a Smith and Wesson Model 66 I have. To get to the serial number, you open the cylinder and it is on the frame. Hard to read but looks like 4K67xxx. No dash. Anyone able to tell me when this might have been made? Also approximate value. It has stainless sights with NO red inset. No box or paperwork but in very good to excellent condition. Thanks for any help. What a great site! Hoowah!
