I have two; Brit. Serv. Rev S#-V161221, and commercial post war .38 Special with S#-SV809978. Photos below.
The SV809978 was lettered and shipped in March 1946 to the NYPD (see letter below) and bears the officers shield # 12095 stamped on the back strap. I had this gun lettered out of curiosity. As a police officer, I carried the same model 10 for many years and thought I recognized the wear pattern and wanted to see if it had been shipped to a PD.
Other photos available.
