Herzlich willkommen

I discovered a little easter egg that I have not seen mentioned yet - if it was, please correct me! I was making a new shifter cover thing - mine was a ratty piece of sheet metal, so this will be better than nothing - and I discovered that my Westfalia fabrik number was stamped on the back! Any other places where we would find this number? I know about the front body above the PTO opening.

Hi Thom,
it's also stamped on the back of the engine covers and the cover behind the pedals.
More I haven't found yet. Did you?
