It is a Marlin Model 49, made for Western Auto.
Mossberg, and it is a version of their excellent 810AH rifle which was made from 1973 to 1977. www.countrygunsmith.net
These guns were made for Western Auto Supply Co. By a different manufacturer. The closest description I could come up with is made by Stevens and is only worth about $200.00 in 100% condition. Hope this helps. I own this very rifle. The Western Auto Revelation 100 is a Mossberg 321. Parts are available from Numrich.
Impossible to answer with any degree of factuality.
If your rifle is a tube magazine type semi auto, it was made under the Revelation brand for Western auto by Savage, and is known as the Model 80. SOME parts may beavailable from a gunsmith, or sources such as gunpartscorp.com. Depending on the parts needed, the cost may be more than the value of the rifle.
It was made for Western Auto by Crosman between 1966-70
This rifle I believe is a .22 caliber. Mossberg model 400 or 402. Tubular magazine made between 1959-1964. Value around $100.
I believe that Marlin made their Model 49 rifle for Western Auto Stores using their Revealation brand.
