The value is about $45 as it was MASS produced and there are plenty of spare parts available.
We have a Ranger bolt action rifle with a model # 103-8. We do not know the age of our gun however.
the ranger Mod 35 was made by savage mod 52B 1933-1937
No such model. Winchester did not make a 'Model 1901 single shot .22 pump-action rifle.' They made a Model 1900, Model 1902 and Model 1904, which were all single-shot bolt-action rifles, and they made the Model 1890 and Model 1906 which were slide-action rifles but had tubular magazines.

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.
Well, My cross reference says the model 34 was really a Marlin 80 which was made from 1935 to 1939. But both the Blue Book and Standard Catalog say the model 80 was a bolt action repeater, not a single shot.
The Stevens model 89,22cal lever action single shot rifle was made in 1976-then discontinued.
50 USD or so
The Ranger 36 cross-references to a Marlin 80 with an adjustable trigger. This model was manufactured from 1935 to 1939.
The ranger 101.8 is a sears rebrand of a Stevens Model 83 made form 1978 to 1980.
