After contacting my Daughter in Austria. Here is the info I have gotten. With a link where more info can be found.
Seems 1 real engine was made and sold to a collector.
Dear Jim !
Thanks for your letter about questions to the BIG COX Babe Bee.
I published this story in my controlline magazin "der LASSOGEIER" No. 93. First this story should be an April-Joke for all my readers. My friend Burkhard Hapke from Bochum/Germany told me before that he has produced an Big Babe Bee for hisself within a few weeks. Normally I have all informations about his work and engines he has made or he has to build in future. Within a year he repaire and restore old modell engines from germany, england and the rest of europe.
As he told me that he plans to build this Big COX I pleased him to do it as an secret because I would make a titelstory for my newspaper within a lot of more jokes (for controlline flyers) in relation to this motor.
And Burkhard has made this one and only engine. It runs and it is really existent. But in the middle of the year 2010, after publishing in LASSOGEIER he sold this Big Cox to a collector.
If you want more informations please looks under
www.kleinstdiesel.de, it is the homepage of Burkhard and he can tell you some more about this engine. His Email-adress is: "email me if you want it..."
I hope I could help you a litte and I wish you a very good new year 2011. Best regards from Germany ! Axel Jungherz
