Default record pista cranks messed up?

just got some older (fluted) record pista cranks, and noticed that the non-drive side arm has a slight bow to it. if you put it face down (away from bike side when mounted) on a flat table, there is about a 2-3mm bow up on one end if the opposite end is flush with the table (it can rock a bit)... just wanted to know if any of you guys/gals know if this is normal or not... the drive side arm is perfectly flat, so i was a little unsure...
thanks for the help,
jordan

Not normal, both arms on this crank are flat.
