Mauser bolt action rimfires
I recently came across a Model ES350B myself. Bottom line : WOW ! It didn't look like much upon first glance. It had quite a bit of surface rust on the metal and some wear on the wood. But I got it at a great price. Neither the seller nor myself knew exactly what it was. When I got it home, I proceeded to take it apart and wipe the metal down with oil-soaked rags and it cleaned up very well. What was once bluing more closely resembles some sort of case hardening colors. Although the wood has numerous scratches and nicks, it is still a very nice example of walnut. Mine is missing the original rear sight also and has been replaced with a Williams rear sight. The bore is mirror bright.

I've yet to determine the accuracy of this particular gun, but from what I've read they are outstanding !
