Toby, the fact that you've never seen a CG with 91-99 should be a clue as to the scarcity of the animal.

Chandler Groves 94 was in mixed production with Strombergs for 1938. Not early, not late, but mixed. CG 91-99 and Ford 91-99 were mixed in production for 1939. There MAY have been a few unmarked CGs make it into early 1939 production, and there MAY have been a few CG 91-99s make it into early 1940 production. There has been no documentation to date that specifically denies those very slim possibilities, but to avoid Concourse day controversy, many if not most guys would rather not push the envelope without documentation, as to do so would surely cost some points. So, for '38, what is known to be correct is a CG or a Stromberg, for '39, a CG 91-99 or a Ford 91-99, both of which may have had an F, an H, or without either.

There is a theory that the 91-99s within a circle* were not original equipment on early '39s. There has been no documentation of this, it is just a theory, and both types are considered correct. It would be helpful if anyone could offer Pro or Con to this theory, and especially if anyone had in his possession a CG having a 91-99 within a circle.

*The circle, or "coin" model designations continued beyond the early years, as the body of the carburetor remained interchangeable while the controls evolved to suit the model year. Model designations on the molds could be easily changed out to a different "coin" as the production need arose, thereby gaining full use of older molds. This production method was particularly useful in the manufacture of service replacement carburetors for previous model years than those in current production.
