Hello,
I'm wondering if anyone has had any experience with this particular engine oil plug. It's marked 1860 then PC and 5, pictures included. Size is about 1 1/4 inch. This is on a 1920 Cleveland Six, Engine Model 40. Plug still works and seals but would be good to know we could find a replacement or equivalent.
Thanks to everyone on this forum for all your help,
- Jonathan
