stevens was a journalist who exposed political corruption
Stevens used the Riverside name from about 1920-1945. It was a brand name used by Stevens for Montgomery Wards and other retailers. They still made some exposed hammer guns at least until 1940.
The Marlin model 24 shotgun was produced by Marlin from 1908-1915.
The riverside double barreled shotgun only came in two models, the 215 (exposed hammers) and 315 (internal hammers). From what I have heard, the 215 should take parts for Stevens or Savage model 215s. However, you can find Riverside parts at http://www.e-gunparts.com/products.asp?chrMasterModel=2680zDOUBLE%20BARREL&MC= A serial number not preceded by a letter indicated the weapon was manufactured prior to 1949. I'd bet (but only a small amount) there is a 3 or 4 digit number on the right side of the receiver which will be the Stevens model number.
This gun was made from 1912-32 and it is valued from $50-300 according to its shape
If your pump 12 ga. has an exposed hammer, it's most likely a model 1898, as all later models of exposed hammer Marlin shotguns had the model marked on the upper tang behind the trigger. If it is not an exposed hammer, then the model designation is on the bottom, where the receiver meets the mag tube.
I'm guessing it is a single shot break open shotgun with an exposed hammer. Made sometime after 1900 and worth $50-$100 depending on condition.
It can be (an exposed negative, exposed secrets). The word exposed is a form of the verb to expose (to reveal).
I find on my Marlin models 336RC that if you lightly oil the bolt,receiver that the bolt rides in,the lever,the extractor inside the receiver,and the exposed steel of the barrel(inside and out)every 3 months when you should do maintinance cleaning that your Marlins will last a long time and give good service.
