Rigid fork for orange P7 1999 420 a-c? F7

[reanimation]

Hiya, on one hand I'd decided to sell my P7 19" frame but no takers yet. It's a bit small for me really, if cheap reliable forks the right length show up I might try it as a commuter anyway. Disc mounts would be ideal but open to options.
F7 fork be a bonus.

Equally open to px swap for bigger frame/set
