I'd say leave em be, my old fully rigid ended up with twisted forks, when the wheel is straight the crown is pointing slightly to the right, but they still track true, the handling is unaltered and for years after they've had some good stick down the woods, I give it some welly, they're fine.

Steel will take the odd bend, its only when you try and un-bend a bend that you compromise the metal.

On the other hand I got some 1" cromo forks as spares for it (just in case) from sjscycles.co.uk, so have a look they may have some kicking about still.
