That would be good. I will be in Baltimore this summer.I found an artist in Baltimore who works in bronze and other metals. I would bet he could fabricate what you need. He does some amazing work.
He was going to hand forge my chainplates when I was still going to do them outboard (not going to now though). I'll ask him when I talk to him next if it's ok to give out his number to you if you like. Let me know.
Brian: I will take some pics this weekend. Thinking about why the chain plates are twisted- I am not quite sure why. They attach to interior bulkhead, then through the deck, then they twist 90 deg, you comment on the toggles is correct. I will take a pic.
