Here is a picture of the crank on the left. The hole drilled in the crank arm reminds me of a truck crank but I'm no expert.

I believe that hole was drilled to lighten the crankpin. Make the rotating assembly easier to balance. I have an original L78 crank, I will check it to see if it has the same hole.
