That idea for a diamond shape was first done in 1910 or '14, and it was called the Scarab or something. I can find my book on it if anyone really cares. I would like to have a bottle of wine and discuss vehicle design with him. Hmmmmm EuroBarf is when?
I'd forgotten about the Mercedes - but it has the same wheel layout as your modern find. I was thinking more of the cars that have been tried for a long time that had that same layout.
Maybe that should be a thread on what really was the first motorcycle.
