Also Restoring This Boat
I'm also restoring a 74 Hunter 25. Finished most of the work last year. Working on the interior this winter and spring. I wouldn't woory about finding original equipment. E.g., original winches were very poor quality. I replaced jib sheet winches with Lewmar #8s. I have old winches in a box (one works the other is broken and in pieces) if you want them. i had to replace a lot of balsa core in the deck. I hope you can avoid that, it a real pain. With respect to deck nonskid, I ground off all the original and repainted with the Interlux nonskid paint additive and was very pleased with the results. I can be reached at sailer7402aol.com if you want to reach me directly. Best of luck!
