Hello Simon,Thanks for posting those very interesting photos. I am not sure what to make of them. I'm not sure they are parts for the W165, my guess is the W196 of the Stirling Moss/Fangio era.I am working to MB blueprints liberated by British Intelligence investigators in 1947. These show an engine with a one piece crankshaft with split main and split con-rod roller bearings. Brian Perkins has found reference to a special Hirth crankshaft being made by Mahle for the W165 with one piece conrods to overcome possible weakness in the big end bearings. Could this be what you have found?The camshaft in your photo, is clearly a four cylinder Desmo camshaft. We know that Rudolf Uhlenhaut designed the 2.5 litre W196 as a staight eight with two banks of four cylinders. As far as I know the W196 was the first venture by Mercedes into Desmo valve gear. My guess is the photos are of parts from that engine. I could be wrong, I am not that knowledgeable about the post war Mercedes cars.Thanks again for posting these photos. I appreciate your help. Research is all about turning over every leaf and analyzing what you find, some days are diamonds, some days are stone.CheersMike
I checked again and the label with the parts says;Mercedes W165Crankshaft and Conrod(both were built into the W165 after the Tripolli Race)

The Hirth crankshaft would most likely be a drop in replacement for the older one piece crankshaft, therefore the leading dimensions would be the same. The W165 has a bore and stroke of 64 x 58. So the distance between the main and big end centres should be 29mm. Also the overall diameter of the crankwebs should be 200mm and the distance between the con rod bearing centres should be 142mm.If this all checks out, I would appreciate if you could make some more photos of the bits, square on and side on so that I can draw them up in 1/3 scale.CheersMike
