further to the above theme. Orenstein & Koppel are still in existence in Germany and manufacture machinery for civil engineering mainly. I am sure that they would supply any information on their history and present products. Their trade mark is the O K inside a horizontal diamond. You will have probably seen it somewhere as there products are distributed world wide. Perhaps their web site can help (not known to me at the minute) I would be surprised if no one has written a book about them. Lots of their NG engines served in sugar plantations, mines etc and many small industrial railroads (rubber) in the far east. There is certainly more info available in the German language - unfortunately.
