i could not find any one anywhere to replace the nylon type bushes on my saddler 25s winches,but was told to go to a local machine shop with a lump of tufnol or equivalent and they made me the perfect part approx cost £40 all in as for pawls etc i cant help
I looked into this last year. The only connection to UK Gibb I could find was an Australian company who no longer sell them. I ended up replacing the winches with Antal self-tailers.
