Ok jeep, just rub it in. Bring it to bulletfest next year so I can bring it home and
inspect it for a few years. At least until you are too old and senile to remember that I have it.
Colt, you have a 1941 Mauser production rifle. It should be of very high quality. They were not loosing or getting bombed day and night yet. The laminated stock is standard. In fact, it is much stronger than the Yugo hardwood stocks. I have one with a Walnut stock, but they made only 300 of those that year. They found that when you butt-stroke someone hard enough, walnut does not hold up as well as laminated wood.
The WaA855, and the "eagles with numbers under them" are Waffen Amts. They are inspectors marks for lack of a better translation. The earlier the rifle, the more marks they usually have, but not always.
If it had an import mark, it would be on the exposed part of the barrel close to the front sight. It wouldn't be hard to see.
I wouldn't worry about the trigger guard not matching. If you really want, you can just replace it with the same type with no number. Just be sure to take note if the edges are beveled or "plain", and replace with the same type.
You got a good deal. Heck, the lousy Russian rebuilds go for more than that. Due to the market being flooded with the Russian rifles (that the dealers are now finding to be hard to sell), the price is a little down. In a few years, it should go up in value quite a bit. In good condition, I wouldn't haggle too much if I had seen that price. In no way did you pay to much.
Hope this helps a little.
