Yes, you can remove the barrel of a model 66 Shotgun!
need a diagram of sears model 66m shotgun for takedown
Stevens model 18D
Whats a sears Roebuck 12gauge single shot serial number 626384 and model number 282 worth
You would have to list the model number of your shotgun,to identify the maker of your sears and roebuck shotgun,in order to get the correct buttstock.
No sn data available.
I believe that your Sears shotgun is a Winchester model 37A shotgun that was made for Sears Roebuck And Co,.
