Is it tube fed or have a magazine?
There was a batch of pumps made by Savage during the transition from the model 1903 to the model 1914. The 1903 had a mag and a regular model 1914 was tube fed but during the switch Savage made a bunch of guns that looked like the 1914 but mag fed like the 1903. Typical Savage using up leftover parts.
If it's tube fed I'm suspecting it's a regular model 1914.
Other Savage rimfires had the same barrel stamp on them, my model 1909 and 1912 have the same stamp.
