I just registered and have a few general and some specific questions. I found an older 12ga side by side and am thinking about buying it if it is in good enough shape to fire with modern shells. From the description it has 2 3/4" chambers, steel barrels(not damascus), and seems to be machanically sound. Generally what should I check? Can I measure the chambers without a chamber gauge to double check? He reblued and refinished the wood himself and looks like a decent job. I'm not after anything fancy. It has no manufacturer on it but it seems to strongly resemble an older stevens such as the 335. There is currently a riverside that looks exactly like it on gunbroker so I think that is what it is. Any tips? Any idea on value?
Here it is


and here is the riverside(which has a disturbingly high asking price)
