Identification Request from a newbie I am a new 336 owner (a little over a year). Last year I bought, new, a 336W. It was my first lever action and I don't care what all everyone is going on about. There is too much passion for the lever action for manufacturing drama. With that all said, That rifle took my first hog in one shot on my first hunting trip this past spring. So We are now bonded. despite the stock is 1/16" short and the forearm doesn't quite match up. It is mine and it is fine. Now, onto my question. I have since purchased two more 336's from auction. They are a 1971 and a 1973 336. Both need some cleaning up. the 1973 has some rust and is now resting in a jar of vinegar (thank you Numrich for parts). I cannot find a proper description of which model. Both simply read 336 on the barrel. I see references to C, RC, CS, etc. When I look at the diagram on Numrich my '336' parts do not match up exactly. Sometimes it seems more like a 'C'. For example the 1971 has the sling mount screwed into the bottom of the band on the Forearm. In contrast, the 1973 has no opening on the band and the front sling mount is a c-clamp tightened directly to the magazine. Is this a matter of personal changes previous owners have made to their rifles? is there a write-up on a plain '336' made during the 70's? Thanks.
