HELP NEEDED!!! webasto gas heater serial #'s wanted

[Schiefer]

Hi again,
Because it is you, I skipped the last part of the Champion League`s match to snap some pics ;-)
Will post the kardex in my project thread when we come to that chapter, but emailing it to you now so you can have a look.

Looking forward to your conclusions, but this is what I see:
- Raised area does not look like hammered by hand, (but no schutz???)
- The lid does look like it has been taken off to be freshened up. Difficult to see, but at least some of the screws (replacement or not) have trace of black paint.

If the pictures are not good enough, I will take more tomorrow in better light.
