I am not keen on this "sauerkraut" term as I prefer Euro or Spaghetti Western :o
I have I believe ALL these Magnificent Classic WINNETOU Films based on Karl May books.
My Absolute Favourites as I posted in my Top 20 are:
FLAMING FRONTIER / OLD SUREHAND 1965 Stewart Granger , Letitia Roman
AMONG VULTURES / Unter Geiern 1964 Stewart Granger , Elke Sommer
RAMPAGE AT APACHE WELLS 1965 Stewart Granger , Macha Meril
The above I would rate as 17.5 out of 20.
Then ALL the WINNETOU with LEX BARKER, ROD CAMERON, GUY MADISON wonderful
