have you ever seen the early BMW posters with the incredible detailed parts in cutaway view by the artist Herbert Schlenzig?

and this NSU engine in the 60's! 


  1. The art work in these cut-a-ways is beautiful. Each one a master piece of its own.

  2. Wow! I've seen textbooks & repair manuals with less detail!

  3. The cam drive on the NSU Supermax, 4th pic from the bottom, is interesting (item 2 in the illustration). It consists of 2 conrods phased at 90 deg to each other (avoiding a dead spot at the end of the stroke). Smooth, quiet and efficient, and despite initial impressions, purely rotary motion so it doesn't add to reciprocating weight. I believe it was quite expensive though.
