The BHK diesels were manufactured from left over parts that Bernhard Helmut Kratsch a relative of Hans Hoernlein sold him after World War II in Suhl East Germany.
Hans was only able to complete a few of these engine before he moved to Voehringen East Germany where he later manufactured the Taifun and Profi model engines. The demand for these engines, simply wasn't there and the anodizing didn't boost the sales at all. Oliver and other engine builders were manufacturing far better engines in the mean time.
