Alvin - The gun was probably made by Harrington & Richardson for Sears. It may be called the model 10 or model 120 in the H&R listings.
If it's really a shotgun and a rifle, I have no idea what you have. Several variations of the Model 1300 and Model 1400 shotguns had the Ranger name added and we would need to know a little more about it to give an estimated value.
Thes guns are not Brownings, but just built on his patent. Typically Ranger pump shotguns sell between $150 and $300
Probably a dozen or more companies made or sold shotguns with the Ranger name, but none would be recognized as a collectable, so if it is in usable condition it might bring $50-$75.
The serial number you posted does not match any data from Ithaca records. The link below is to the accepted table of manufacturing dates for Ithaca shotguns. Values can range from $200-$450, depending on the exact version and the condition.
Shotguns marked RANGER were made by several different manufactures before WW-1. They were sold by several different hardware/catalog stores including Sears. Value is uniformly low, under $200, typically as a mantel decoration.
Perdy - never heard of that maker Purdy - you need the services of a professional appraiser who knows shotguns.
