Picked mine up today. Good stuff.
I ordered 3. One from each Arsenal. I received exactly that.
There are three major differences between this batch and the previous. The older orders had a "plum" coloured refurbished bolt. The new ones are more "gold" in colour. The second difference is the DE09 on the receiver near the date and arsenal. The third difference is with the trigger. The previous ones had a lighter trigger on average. The triggers on this last batch are still clean and good, but they are heavier.
You never know what you're going to get with these orders. With the previous orders I had a Tula 1940 with an incorrect muzzle brake. It had the 2 ports instead of the 6. Everything else was good. With this new order the Ishevsk 1941 came with the incorrect muzzle brake. No big deal but worth noting.
All three have the correct SVT-40 stocks. no AVT replacements. One of them has zero stock fixes. The other two have minor arsenal repairs. With the Ishevsk having the most repairs.
The Tula has really nice looking darker and kind of blotchy wood. Looks very good. I like it. The other two have your regular colouring for the stocks.
I figure if you've read this far you are really interested in these rifles.

. So here's the interesting thing:
The 1941 Kovrov has zero arsenal repairs on the stock but does have an extra pin in the rear near the receiver. But more interestingly is the fact that there are (4) ###x marks on the stock left and high of the serial number. The letter X isn't in the serial number for this rifle. I'm wondering if this was a "sniper" variant? It would explain the 4 x on the stock and the extra pin in the rear near the receiver for extra stability even though there are no repairs.
Did the Russians use an X on their stocks to mark sniper kills? Or is it some type of proof mark?
