I picked up an Airweight today after looking at it for 5 consecutive Saturdays. It has the snub barrel, diamond grips are stamped to match, flat latch. The SN#351562 is stamped on grip frame, under barrel and on cylinder face..cylinder is steel. The large S&W logo is on right side. No model number..but there is a K and assembly number 37865 on frame and 37865 on yoke. I would would rate the condition at 95%..no box. I paid $325 for the revolver. Any ideas on DOB? I will post pics later.
