The Word ranger was used by Winchester to denote a economy version of there regular rifles and shotguns.The model 670 was a economy version of the famous model 70 bolt action rifle.Winchester also made a ranger model 94 rifle,and various ranger model shotguns during their many years of being in business.
Marlin is about same as model 81
This bolt is the same one used in the Winchester model 57, 69 and 75 rifles.
don't take down a Winchester model 52, the way they bedded the rifle was a mystery. It may never shoot the same if you take it apart.
Search on youtube for Winchester 1300 assembly, they are internally the same.
Your Sears model 54 is a Winchester model 1894 rifle that was made for sears.If Winchester used the same serial number sequence as their serial numbers for the Model 1894,then your rifle was made in the year 1955.
I can say that the model 1200 Winchester shotgun was made from 1964-1981.The model 120 ranger was the entry level shotgun to the model 1200.Winchester did not keep records of the serial numbers assigned to the years of production of the model 120 ranger shotgun,but I can assume that yours was made during the same time span as the higher level model 1200.
The sears model 6c-22 was made Winchester/ same as Winchester model#490
Marlin Arms. Same as Model 81
This rifle is the same as a Marlin model 80
The same as your Winchester rifle.
The Winchester "Ranger" Model 120 is by all accounts the same as the Model 1300. There is a free dowloadable manual at: http://www.winchesterguns.com/prodinfo/om/index.asp Hope this helps.
You need to find out what model your Winchester is. Just knowing the caliber won't do. The same serial number will exist on almost every model. If the rifle is a model 670A it was an 'economy' version of the Model 70, sold in department stores. Value today at retail is $250-$300.
