Hi Merlino,
I think it is the KK-70 figure of Ludwig XI. von Frankreich from the Karl der Kühne series of Gottstein.
(however I also read that it was a later addition to the set by Blum or Kollbrunner)
It is quite hard to find - I know it because I myself is hunting this figure for long.
Last time I saw it as a lovely painted figure of Mr. Eric Talmant, but unfortunately I lost the auction that time.
It was 1-2 years ago - since then I did not see it.
I would be also interested in buying one.
Good luck-
Sandor
