This is one of the early Barry Grants when he use to take Holleys , do some mods and stick his decal on them. After Holley took him to court for Patent infringements , He came out with the Demon line of carbs.
His early models that I have seen and have actually used had "BG" engraved by hand on the body. It is the only way I know to tell if it is the early stuff.... And the early stuff worked pretty good. My BG dominator was a bad **** lol....
