back in the late fifies/early sixty's bike shops use to have steel block jigs that you could lay a damaged fork into and bang it out to original conture. it would seem that this fork would be a candidate for that kind of repair. i damaged a 1958 raleigh lenton fork, similiar to the damage on the bike you show, and the bike shop straightened it in a matter of minutes. of course that was old school when things were repaired verus replaced like in today's culture.
