This is an extremely hard to find original diecast governor bracket for a Fairbanks Morse Z engine. I believe it is for the 3 and 6hp engines. It mounts with 2 holes 4 7/16 inches apart on center. It is NOS, new old stock with no cracks, breaks, or repairs of any kind and fresh from the unused inventory of an old hardware store. Everything turns and interacts as is should with no noticeable wear. It is ready to be used on an engine. It would also make a great spare on the shelf. Let the pictures be your guide. I highly doubt there’s many NOS ones left to be found in the wild!
