We have a 1983 Californian 38 and our teak rail hardware was made by Perko. The hinge is part 180-1. These are no longer made. The best way to find one is to place a saved search on eBay and maybe one will be listed. I have been looking for 4 months, with a saved search for that part, and luckily a group of Perko railing parts showed up! Win!!
