Crankshaft advice

[David Stepney]

Close examination of the third picture that Parazine posted initially appears to show a drilled hole at the bottom of the right hand crank trough. The left hand trough's lower end is partially obscured by the edge of the trough itself, so any drilling there is not apparent.

I think that the crank in question is indeed a splash fed crank. I am sure, though, that Parazine will confirm one way or the other.
