MAY 18 Engine production records, Ford Archives

Engine 6,000,000 built at 9:14 A.M. Given to Edsel Ford.

“The six millionth Model “T” Ford motor was produced May 18th, in the Ford factory in Detroit. In other words, from the time back in 1908 when the Ford Motor Company began marketing the now famous Model “T” Motor Car until May 18th, 1922, a total of six million Ford cars and trucks have been produced. Out of this total, 5,517,956 were delivered to purchasers in the United States alone, and according to the latest statistics, 4,478,248 of these Ford cars and trucks are still in daily service.

“Thus, it will be seen that one out of every five Ford cars and trucks sold to retail purchasers in the United States alone during the past fourteen years, four are still in actual daily use, which is really remarkable when the hard service of commercial cars is taken into consideration. This seems to forcibly confirm the popular knowledge of the longevity of Ford cars.

“That Ford products have been quite evenly distributed throughout the United States is borne out by the fact that thru the sparsely settle communities in the West to the densely populated cities in the East, practically the same ratio of Ford cars and trucks to population exists.

“Ohio leads with a total of 290,769 Ford cars and trucks in daily use; Illinois comes second; Pennsylvania third; Texas fourth, and Michigan fifth, with a total of 234,081. New York, Iowa and California follow in the order named, each having more that 200,000.

“An idea of the important part played by Ford cars and trucks in the daily transportation of goods and persons in the United States can be gained by realization of the fact that with the Ford cars now in operation, averaging a minimum of 5,000 miles per year each, they would pile up a total of Twenty-five Billion transportation miles — equivalent to more than a million trips around the world.

“Ford Motor Number 6,000,000 was lifted from the assembly line in the Highland Park Ford Plant at 9:14 A.M., May 18the.Just 5-1/3 seconds later Number 6,000,001 was finished.”

JUL 14 Engine production records, Ford Archives All engines now use rolled-thread head bolts, first used beginning March 31, 1922.

OCT 10 (Letter from Louisville Branch)

New Fordor Sedan described. Price: $725, FOB Detroit. Dealers asked to not advertise it and to sell it only when the standard (centerdoor) sedan could not be sold to a customer.

“A new four-door, five-passenger sedan body has been added to the line of standard Ford body types. This body is an entirely new development in design and construction, and does not in any way displace the present two-door sedan, which will continue to come thru.

“While this new four-door body will go into production within the next several weeks, the output will necessarily be limited for some time to come; therefore your sales effort on the present two-door type should be increased rather than relaxed. This present type still represents one of the best automobile values on the market, and the new type of body will simply broaden the field of sedan prospects, so far as Ford business is concerned.

“The price of the new four-door sedan is ($725.00) Seven hundred and twenty-five dollars, F.O.B. Detroit, and the differential between it and the two-door type is large enough to prevent competition between the two models. There is no reason why you should lose a single sedan order because of inability to deliver the new type, WHICH SHOULD ONLY BE MENTIONED TO PROSPECTS WHO HAVE PREVIOUSLY GIVEN CAREFUL CONSIDERATION TO THE PURCHASE OF A FOUR-DOOR SEDAN, AND WILL NOT BE SATISFIED WITH ANY OTHER TYPE. (sic)

“Continue pushing the sale of the two-door sedan, and only accept orders for the four-door type to prevent actual loss of business.


“Attached is a description of the features of the new four-door sedan, and a little later it is expected that a descriptive folder with illustrations will be ready for use.”


“The body is approximately three inches longer than the two-door type Sedan, the extra length providing additional leg room for the occupants of the rear seat.

“All body panels are of aluminum with embossed molding, the metal extending up around the window sills and runways so that there are no wood parts exposed on the entire body. This feature insures a uniform finish and will largely prevent checking or other paint trouble.

“The body though longer that the present design weighs approximately 80 lbs. less. The saving in weight is gained by the use of aluminum panels in place of steel and also a lighter roof construction.

“The roof is of the soft type with artificial leather reinforced and padded, making it as durable and substantial as the old fiber board type, and eliminating the possibility of vibration noises. The overall height of the body is one inch less that the present design. With the straighter roof line the car has the appearance of greatly increased length.

“A permanent leather visor above the windshield adds greatly to the appearance of the car while protecting the driver from the glare of the sun.

“The tire carrier is of a new and improved design which permits the spare tire to set at an angle that corresponds with the lines of the body.

“The front door openings are 23-4/8 (sic) inches and the rear door openings are the same width as on the present two-door sedan.

“Door handles are of the straight bar type made from hard black rubber with nickel tips and fittings. All doors are equipped with locks. Three of the locks are operated by levers from the interior of the body while the right front door is operated by a key from the outside.

“All doors are equipped with special Ford design double roller dovetail guides at center as well as rubber bumpers top and bottom to prevent rattling.

“The upper sash of the windshield is adjustable either outwardly or inwardly to provide the proper degree of ventilation. An improved design of clamp permits it to be easily adjusted and securely fastened in any position. The lower section of the windshield is stationary which is a factor in preventing rain from leaking into the body.

“The windows in all four doors are operated by means of crank type window regulators, while the rear windows are operated by the present lever type used in the two-door Sedan.

“All interior fittings, including window regulators, door pull handles, door latch levers, etc., are finished in oxidized silver.

“A dome light is operated by a button on the right rear body pillar.

“Upholstery material is of improved design with a fine dark stripe on a brown background of a shade that will not easily show dust and dirt. Silk window curtains to harmonize are provided for the three rear windows.

“The rear seat cushion is 46-1/2 inches by 20 inches, or one inch wider than in the two-door Sedan. The front seat is 42-1/2 inches by 19 inches and will accommodate a third person if necessary. The front seat cushion is divided in the center making it necessary to raise but one-half of the cushion to fill the gasoline tank. Therefore, the driver may have the tank filled without leaving his seat.

“Seat cushions are held in position by means of dowel pins in place of the covered binding strip used on our two-door Sedan.

“The price of the new Sedan is $725.00 F.O.B. Detroit.”

OCT 26 Acc. 572, Box 21, Ford Archives An assembly and changes letter to the branches states the new four door sedan then in production in limited quantities and that small shipments will be made to assembly plants this week.

OCT 27 Acc. 78, Box 48, Ford Archives “There will be a change in the stripe (on the Fordor Sedans), using the ivory (supplu of which we are preparing) instead of the carmine stripe used on the coupe and two door sedan.”

OCT 30 Acc. 78, Box 48, Ford Archives FORD’S QUALITY CONTROL(?) Coupe bodies

“We have just discovered that in order to make the door panels fit on the coupe jobs, some workmen had conceived the idea of cutting the cardboard on each side about 1/2” from where it was sewed to the cloth and extending from the top to the bottom, thus permitting the cloth to be stretched so that the full surface of the door and door frame would be entirely covered.

“As soon as this was discovered we checked up and were assured by the Briggs Manufacturing Company that this did not extend over a period longer than two days.

“By feeling along the sides of the panel it can be easily distinguished whether or not this cardboard has been cut and wherever you find it necessary, out suggestion is that you replace the panel with a good one from your service stock.

“If the panels which you remove can be used for service and if you have only a very few of them, our suggestion is that you put them into your service stock. In any event, advise us of the number your replace, so that we can determine whether or not they are to be charged back to the Briggs Manufacturing Company.”

The letter does not say what to do when you get one of these defective panels from service to replace another defective panel on the coupe being repaired!
