if it is just coppery may be lucky and get away with a polish, worth checking out .

il let you know in a couple days as im having a crank ground at the mo. il ask the engineer what standard crank size is when i collect it.
he has a book with all the crank diameters etc, surprised the guy whos doing yours does not have this info!
