I noticed also that it is misspelled, googling that exact spelling did show a couple of very old ebay auctions, but the auctions were not accessible when you clicked on them, so I could not see if they were exactly the same as my one.
From the details that were available via the google search, one seller said German and 1960's, that might account for the misspelling.
Certainly an interesting and detailed piece nevertheless, would have been nice to ID the piece, but I think this will be another mystery :-)
