WTB:Columbia AG mandrel and shaft

[pallophotophone]

Hi,
I just acquired a Columbia AG . but in shipping the end of the mandrel where the shaft is press fitted into it, is bent and the mandrel wobbles and it hits the cast iron support . Unfortunately the mandrel is only supported at one end
Does someone have a spare one in fine condition they'd sell me ? A long shot, I know.

Many Thanks !
