Hello,
I am restoring a 1915 557cc engine which needs a new piston.
The current piston is not the original and may not be correct.
I need to confirm the measurement from the gudgeon pin to the top of the piston (flat top)
Would anyone have any copies of original drawings/details/measurements of the pistons,particularly the height from the gudgeon to the top of the piston?
Thanks
