At first, I agreed with Bill; but, thanks to GM's Heritage Center's down-loadable library of Specifications Manuals, it looks like Tom's truck might well have a
1938 truck serial number in a correct format? (
Here is a PDF version of that ID page) T1723577
T = 1.5 ton truck from Flint Michigan assembly plant
1723577 = 1187822 (first truck serial number in 1938) = 535,775th truck out of the plant that year?
Does this look right?
195447 is the first engine serial number in 1939. So, maybe Tom's code is good for 1938?
Tom, can you find any date casting codes on the block/head?
