Karl Bub Tin Lithographed Key Wind Clown Car

Karl Bub Co. West Germany. 1950's era. Not much info on this strange toy. Karl Bub made tin toy cars and trains of a high quality from 1851 - 1966.
This clown and same clown riding a rocket were most likely the last of the Karl Bub toys manufactured. Features on this toy include, creepy clown driver, key wind motor , sparking feature at rear that uses Ronson style lighter flints to spray sparks as car rotates. Missing original BUB key to wind, but can be wound with similar sized key. Excellent condition graphics. Survived unused most likely. Has dent area, but most likely from rolling off a table or ? while chasing small children. As creepy as he is, I think I will try to find the version with rocket as well. Feel free to comment on any info you may have eg Clowns name, date of manufacture etc.
