I bought a dinged up, gunked up (but not frozen), rusted machine early this afternoon. We're having a very large rain storm in this area and he was storing it *outside*.

("Don't worry, it's under an overhang!", he assured me. Do people understand the concept of humidity and moisture in the air all around them?)
Here it is:




The text on the slide plate:
"H. Nawratil
Mechaniker
Wien
VII Burgasse"
Serial #: 409325
Medallion says: "Schutz Marke"
I've Googled for about 20 minutes and couldn't find anything. Wien == Vienna. So it's possibly an Austrian machine?
The decals are shot. This is a complete refurb including a strip, sand, fill, sand, prime, sand, paint, sand...etc. I have no idea what I'm getting into but I blame all of you for getting me so deeply into this hobby.
What is this gross machine?
