I just got this from my father as a "B" Day gift and cannot find any info about it on the web.  I'm guessing that it was made by Winchester for Sears and Roebuck.  Anyone have any info like general time it was made and sold at Sears, approximate value.  I've looked it over and it's in great shape.  It also has the model number #273 2341 stamped on the barrel.

Thanks for any help,

According to my very old and trusty Gun Parts catalog, your're spot on in your guess, NeedAclip.

It showns the rifle as being a:

House Brand Sears M5,M-5T;
Model# 273.2341;
Orig. Mfgr. Winchester;
Orig. Model 150-250.

Good luck and enjoy your Dad's gun.
I recently happened to acquire my Dad's .22 that is a Winchester bolt-action 'J.C.Higgins' made by Marlin as a model 81; it's currently getting the stock refinished.
Then, in one week, I got my late Dad's post-64 .30-30 Winchester model 94 in rough condition AND my late Step Dad's pre-64 .30-30 Winchester model 94 in good condition!
I can't believe my good fortune.

The post-64 is gonna be upgraded in the refit.
The pre-64 will remain in original condition.

Anyone getting a family heirloom is in for a real treat.
Have fun.
