The serial number indicates it's a 1946, but it's missing the first number/s for plant identification...
DBA554708 here's the way I see it,
x = Assembly Plant (1 = Flint, 3 = St Louis, 5 = Kansas City, MO, etc.)
D = 1946 second design (C = 1946 first design, E = 1947)
B = this is a typo, could be P which is the 1/2 ton truck
A = Month (Jan)
554708 = Unit number
