The German uncut version was always shown in 4:3 from the same old print until 2002 and for one more time in 2014 on BR (Bayerischer Rundfunk). There has never been a 16:9-airing of the uncut version, so this must be a fanmade edition.
However, I think it would be great to get the open matte-version scanned in HD from a 35 mm-copy. The German uncut-scenes could be inserted from the 2014 TV-airing. But the auction on eBay is already on more than $1.000 and it keeps on going until tomorrow…
