You can watch ebay for forks, but before I did anything I'd talk to a local framebuilder
and have them double check the frame.
If the fork was that badly damaged I would be very surprized if there isn't damage
to the frame.
Can you take detailed pics of the top tube and down tube just behind the headtube?
any bulging? cracked paint?
really nice bike. . . even if damaged might be worth it to have your
friend fix it.
