This rifle was introduced in 1928 and produced until about 1940. Total production was therefore limited. Its sibling was the Model 45,
an upgraded model that had a checkered stock and a receiver peep sight. They were offered in .30-06, .300 Savage, and .250-3000.
The Super Sporter replaced the earlier Savage Model 1920, a fine rifle whose action was too short for the .30-06. The most interesting feature of the
Mod 40/45 was that it had locking lugs at the rear of the bolt, a departure from the much more common Mauser practice of lugs at the front of the bolt.
I have a 40 that had inlet probs which Ifixed by epoxy bedding and it is now very accurate. Your serial number would indicate production toward the end of
production.
