Serial Numbers

ENGINE SERIAL NUMBERS
The engine number was also the serial number of the car. Engines were numbered when they were completed, and for the most part went into a chassis within a day or so. However, some engines were assembled and numbered at branch assembly plants. Highland Park would ship a block of engine-number records to an assembly plant and these engines might be made weeks or months afterwards. Consequently, engine numbers can only be used to date the “engine” NOT the car.

It might be interesting to note that Ford claims to have built fifteen million Model T cars; this figure based on the number of engines. Records show, however, that a good many engines were made which did not go into a car, perhaps being for replacement or other use. Fifteen million, of course, is an approximate figure. Add the thousands of cars made in Canada, which are not included in the U.S. serial numbers, and the fifteen million is a reasonably safe number. (Canadian serial numbers, beginning about 1913, generally begin with a “C” and were not a part of the U.S. count. Prior to 1913 Canada used U.S. engine numbers.)

A comprehensive daily serial number list, with many notes, is included in the book, Model T Ford. That list is about 150 pages long, much too large to make available on this site.

* Numbers shown are based on the dates of sale, not of manufacture.** The actual dates of manufacture of engines before 1913 have yet to be discovered. The numbers shown are based on the dates of the sale of the engine/automobile. From the available data it appears that engines were installed in cars, or sold as engines only, in numerical order until summer of 1912. In late 1912, however, engines were assembled and numbered, and then stored for later installation. Consequently serial numbers and dates are no longer in order.

In the summer and early fall of 1912 engines were made in a separate plant (only known as “Detroit” in the records, and these engines were given “B” numbers 1 through 12,247. These B-series engines were installed in random order beginning in October and ending in December 1912. To add to the confusion, there is a gap in the regular serial number sequence of 12,247 numbers, somewhere between 157,425 and 170,000. We have found no evidence of engine numbers in the 158,000 to 169,000 range. During these three months, a mixture of the B-numbers and the regular numbers were used and by the end of December all the B-numbers were used.

It appears that the engines of this period were warehoused and removed at random, sort of a last in, first out sequence. For example, B-numbers in the B-1,000 to B8,000 range were used in October, B-7 to B-12,000 in November, and B-5,000 to B-12,000 in December.

Ford’s records show 157,425 as the first number of fiscal 1913 (October 1, 1912), yet cars with engines in the 153,000 to 157,000 range were sold in October (in addition to the “B” engines). 169,### to 173,### in November, and 169,### to 183,563 in December.

Beginning in September 1924 Ford began producing engines at the then-new River Rouge plant. Initially Highland Park would send the Rouge a block of engine-number records and these numbers appeared on engines built at the Rouge. As Rouge production climbed, Highland Park’s declined and as the Rouge became the primary source they would send blocks of number records back to Highland Park. The result of these two production sites was that there is no real numerical sequence in engine numbers between September 1924 and February 1925. The daily serial number lists published in Model T Ford, the Car That Changed the World shows the days on which certain engines were produced but this abbreviated listing does not.
