Mallory made a number of different models of carburetor; the model F is the most common. Strictly A/M. Sold through such sterling establishments as J.C. Whitney, etc. to those individuals too frugal to purchase a rebuilding kit for their original carb.
Somewhere, I have some original Mallory literature. I believe they offered A/M models for Chevrolet, Ford, and Plymouth in the late 1930's and 1940's.
We have several, fully restored. I once thought they would sell to the guys building nostalgic hotrods with multiple carbs. So far, have sold one only, to a friend who used it to finagle a Mallory dealership when Mallory put together a mini-museum. I probably have more in the restoration costs (plating, machining of parts, etc.) than the stuff is worth.
Since I have always believed honesty is the best policy; I will sell you one if you wish. However, it is my opinion you would be better off with a Rochester B with about 3 million miles on it (and you all know how well I like the Rochester B ☺ ).
