I have a 4x2 manifold for a flathead ford . It shows it as a Baron manufacture with what looks like a serial number of 101. It has stamped B4C 101 on it. I was told this was a prototype. When I contacted baron racing about it in 1995 they sent me a letter that I could trade for anything they had even up. I still have that letter. I cant prove it is a prototype but I dont believe it has ever been ran on an engine. It comes with 4 carburetors. Not sure of condition. 2 are stromberg and 2 are fords. They are models 97 and 8BA . I think they are late 30s types. It has a one style linkage but all are not hooked up. Being sold as is , the manifold is rare and the carbs are a bonus. Includes 4 carb scoops too. Everything you see in the pictures are included.......ITEM IS SOLD
