Many thanks in advance.

I found some, that seem to be the same, that are fairly similar if you remove the decoration. Try the Winderrar-Bold, Kastellar Bold, Outline4, Haute, Kaste and Nelson. Apart from Outline4 and Nelson no author names are known. Arts & Letters claims the Outline4 and Brendel Informatik claims the Nelson.
Both Arts & Letters and Brendel Informatik though are well known for copying fonts.
