I have a set of these forks and had them powdercoated, that rust on yours doesn't look too bad. If you don't fancy that, I actually have a new old stock set of these forks that I bought for spares, but haven't used since getting them. They have a few scratches etc from storage but are in good condition overall and not having ever been fitted or used, will last for years to come. I may be interested in selling the fork, perhaps even just the lowers.
