Three Different Crown Stamp Variations

This is the Mauser Oberndorf Crown. The bottom line is a bit sagging, as can be seen in the picture above. Screws for these rifles were marked with an "M" symbol.

Next is the Carl-Gustaf crown stamp. I wish I had a better picture, you have to click it to see it in a bigger size. It can be recognized by its straight base. I have seen at least three or four different variations of this stamp - shape and size differs slightly.
Last is the Husqvarna "slanted" crown. Note how it is applied leaning to the right. The rifles made for FSR civilian shooters, as well as the m/38 rifles manufactured by Husqvarna Vapenfabriks Aktiebolag have this symbol.
