I have a sears robbuck mod.3T cal. 22 S.L or L.R. automatic. What year was it made and how much is it worth?

I bought one back in the late '60s for about $90.
I believe these rifles where made for Sears by Winchester, as they sold one at the time that was almost identical. I frequent gun shows and haven't seen but one besides my own. I suspect they have little collector value and shooter interest, as the tubular magazine is cumbersome to load. The Ruger 10-22 put my Model 3T into retirement years ago.
I would guess these rifles would sell today for between $100-150 for a good clean one.
