Engine numbers

[Steve Jelf]

From Bruce McCalley's encyclopedia:

1909
(Early water-pump engines) Ser. # 1 to 309 calendar year 1908
1 to 2500 model year Model year (Oct. 1908 to May 1909)
S/N (serial number) located between the center exhaust ports.

1909
Ser. # 310 to 14,161 calendar year 1909. 2501 to 8,100 model year
(Model year May 1, 1909 to July 31, 1909.) Note: Ford’s published data shows 1 to 11,100 built between Oct. 1, 1908 and Sept. 30, 1909.
S/N on boss behind cam gear housing on right side of engine.

This was the location of the serial number until about 100,000 when it was moved near the water inlet on the left side [in (February?) 1912.]
