This kit was produced in the 70s in East-Germany (better known as GDR ) and was the first steps in kit manufacturing by Max Krätzer (=MK Modelle). I don't believe that they had a license to copy from original Pyro pattern, so it is more a not legal copy of the kit. Two kits of this types were produced, the "Texan" and the "Jersey Bounce". For more Informations about kits from MK-Modelle I have created a Facebook site. https://www.facebook.com/pages/MK-Modelle/532990283393483?ref=hl
