The earliest production CVA mountain rifles had nicely faceted ramrod pipes. The later production made in both Conn. and Georgia, had plain pipes with just a groove around each end of them.
Always inspect the drum, and nipple, carefully, when cleaning any CVA rifle, or pistol, that has the drum, and nipple, configuration. When I got my .50 Cal. Mountain Rifle almost forty years ago, I shot it every day after work. I just couldn't get enough of it. One day I noticed that just behind the nipple the wood on the stock was charred, and burned away a little bit, down near the edge of the lock plate, just under the hammer. I took the stainless nipple out, and inspected it, and found the threads on one side burned off, just like they had been cut off with a microscopic cutting torch. Upon inspecting the inside of the drum I found the threads in the drum were also gas cut. This is a very dangerous condition that could result in injury, or even death, in some instances. Always inspect you CVA guns for this, and check any you buy used.
