SO:ġ: cast your net wide: post to every old truck site you can find, every fire/fireman/fire truck site and the farm /tractor sites too (old iron collectors often have wide interests) Ģ: salvage yours? Unless the bakelite is cracked or the contacts worn beyond use, carefully cleaning the contacting surfaces might work.
I'm not familiar with these, but if I understand your post only four of those engines built, or only four with your specific dist's? Even assuming the engine continued in production with your dist's, it's probably a low total prod engine, which makes finding parts mostly praying for miracles.
