need a diagram of sears model 66m shotgun for takedown
I believe that your Sears shotgun is a Winchester model 37A shotgun that was made for Sears Roebuck And Co,.
Stevens model 18D
Yes, you can remove the barrel of a model 66 Shotgun!
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.
Probably Harrington & Richardson
