Most of the typical Bronze hardware - blocks, cleats, etc. look like typical Bristol Bronze type stuff - so you should be able to replace what you need through them, Spartain Marine, or if you want to upgrade try Reineck. The skeg will be far more difficult - If I remember folks that had to replace had them fabricated. I think I remember a foundry in Washington state that did some - Maine as well....You can try to find one locally that will cast in marine Bronze. Call Herreshoff designs and see if they have the actual specs for the piece you could take to the foundry....
