Coupe body had apparently been modified to have the gas tank
under the seat in part of 1920 production. Directive advising of change back to
the square tank in the rear deck made this date. The height of the coupe seat
seemed to be the problem.

The following letter was received from the Holley Carburetor Company: 1. A contract was made between the Holley Carburetor Company and the Ford Motor Company, September 1, 1920, in which the Ford Motor Company was given a shop right to manufacture our NH carburetor, the consideration being orders to be placed with us for 50% of the carburetors used on the Model T cars. From September 1st to June 30th we received orders for 34% of the cars produced. 2. We installed machinery to produce 5,000 carburetors per day. The above contract provided for one year's notice of cancellation. This notice was given us on April 21st, 1921. Since that time, machinery has been installed in the Highland Park factory to produce carburetors known as Model F, which is identical with Model NH with the exception of a slight change in the mixer chamber venturi, as per sketch attached. We are informed that they have orders to produce 3000 of these carburetors per day while we have never produced more than 1,800 per day and have been laying men off a portion of each month. "We spent about seven months and very nearly $75,000 in perfecting the NH carburetor and so far as the writer knows there are not complaints on workmanship. Our price has been from 11 to 30 cents per carburetor lower than Kingston and, to the best of our knowledge and belief, it is also lower than the cost of the Model G made at the Rowena Street plant. Our relations have been cordial and satisfactory in every way and we are at a loss to understand the reason for the action taken at Highland Park as it is absolutely unjust and only leads toward an organization that will permit such action to be taken." There is an attached drawing showing the venturi designs for the NH and Model F. The NH has the "straight through" bore while the Model F has the venturi that dips in the middle ¾ what we usually think of as the later NH. It is interesting that the Ford built carburetors had this feature earlier than the Holley. The Holley letter was accompanied by a letter from F.H. Diehl the Ford Motor Company's purchasing agent. He stated that not only was Ford making Model F's, but that they were building Model G's as well. And they were buying Kingston's too. These documents suggest that Model T's came with four different carburetors from Sept. 1, 1920 to Aug., 1921: The Holley NH with the straight thru design, the Model F, the Model G and the Kingston. (The above was discovered by Trent Boggess during a visit to the Ford Archives in February 1997.)
