First Welome to G & G,
The Model you have was produced between apprx. 1938 and 1954.
Not sure where you would find a manual for Savage 7. But if you see a manual for a Savage 6 or Stevens 87 try that, they are similar except for having tubular magazines.
Savage doesn't have it listed, but you might try them for a manual. You'll have to request it and just see what they say.
