My first model 99. Seeking info

[surfj9009]

Hey guys. I just traded a Kimber 1911 .22 conversion kit for my first lever action. Looks like a nice gun to me. Curious if someone can tell me how old it is or any other info. It's a 300 savage with a rotary magazine.

Serial number: 3621xx
Has a SP in a circle on the left side of the receiver. ?

1937 or 1938
