My Schienendrilling is an ESHA 'Waldläufer', a 16b boxlock with 22lr in the rib.

I really like it a lot and it's been very handy here on our ranch.
With a couple roundball handloads, a pocket full of shotshells and some rimfire ammunition, I'm set for just about anything from packrat to mountain lion.

NewGuy, I'm excited for you on this project.
Have fun with it!
I'm sure any/all of your clients will enjoy the neat little guns.

Cheers
Tinker
