Thanks for all the help. Called Remington and the mfg. date was 1954.
Also, I had measured the barrel wrong (told ya'all I was new to shotguns).
The actual length is 18 7/8". Overall length is 38".
The Rem rep. said it was a 16 guage Riot.
Once again, thanks for the help and I will check into buying a longer barrel for some hunting.
