His comments may be totally correct or totally wrong or something in between. Some of his claims seem to make sense some don't. Interesting and a good website though.
I will stand by my belief that this rifle has not been fired. All the etching of the serial numbers was done AFTER the parts had been blued. Also all the stamping of the serial numbers and proof marks are raised and sharp. Inspection of the components under a 50X scope indicates no disruption of metal or surface finish on the bolt, carrier, etc. that would occur under firing. Even with the naked eye one can see the very fine machine tool cutter marks and sharp edges from milling are still there. Under a 50X you can damn sure see it. I worked as a machinist and toolmaker for years and I know a fresh milled piece of steel when I see it.
Although there are no arsenal rework stamps on the rifle itself the buttstock has the square with a diagonal through it on the right side. IF the laminated buttstock was installed later, which it could have been, nothing is impossible, then it was a new stock and serial numbered to the rifle perfectly. Not restamped, etc. However the laminated stock wound up on the rifle it sure is a beautiful piece of wood.
It doesn't make a lot of common sense to me that the Russians would have taken an unfired SKS out of storage/inventory and put a new stock on it and then put it back in storage. It also doesn't seem logical that the Russians would determine a problem with the stocks cracking, make an engineering change, use the change for arsenal rebuilds and continue with production without implementing the change?? Of course anything is possible with a bunch of Communists drunk on vodka. After all, they are first cousins to John Kerry and his socialist ilk.
I will stand by my claim that I have never seen a nicer SKS and I have seen a lot of them. All the history is interesting and trying to gleen it accurately from a 50 year old rifle is likewise a challenge.
