Thes guns are not Brownings, but just built on his patent. Typically Ranger pump shotguns sell between $150 and $300
I believe Mossberg made the Coast to Coast branded shotguns. I know they did while we owned our store.
Your gun is a Stevens Model 520. Made for Sears, and marked with the Sears trademark of Ranger. Nice pump shotgun, originally designed by John Browning.
The winchester model 42 was a .410 pump very like the old model 12 pump
The Marlin firearms company produced pump action shotguns from 1898(the Marlin model 1898)all the way up to 1985(The model 120 Magnum shotgun).during that time span Marlin made 17 different model pump action shotguns.

There are a lot of Sears Ranger rifles - what is the Ranger model number?
1958 - 1970 I was told
That is not a model number, but is likely the serial number. Unless you have a Model 620 US marked Trench Gun, Stevens pump shotguns have little collectors value.
im almost certain its remmington Stevens Model 520
Winchester made these pump action shotguns in there New Haven Conn.plant from 1964-1981.
