I think the DBA number is an engine serial number.
D = second series 1946
B = 3100 series (1/2-ton)
A = Flint engine plant
Before 1955 many states title vehicles using the engine serial number.
I looked at the pictures and it’s definitely an Art Deco style truck. Production of these trucks continued into 1947 and many were titled as 47’s.
Frank, I think you solved it...my head took me to the chassis number, not thinking about the engine number. With the high unit number it makes more sense now...they got the info off of the title!
