Just got an interesting mail from one Tom Bridgers.
Seems he is the proud owner of one of the hand-built by Heinrich "Henry" Dirrigl DOHC RS 54 replica boxer engines - only two of these were made.
He is looking for information about the FRAME/CHASSIS that the RS54 was equipped and raced with from the Factory. My research has not found any images of the RS54 with tank and seat removed to "understand" the construction of the frame, let alone any of the dimensions.
If anyone would have such an image, or information regarding specifics, dimensions, or construction of this frame, factory drawings,
or any sources or leads to find such information, please contact me.
thanks in advance.
