Hy uncle buck, the serial number on that truck breaks down as follows
1 = 1951
17 = series code 3 ton, largest Chevy truck produced this year
83 = model code 179" wheelbase
01233 = regular production number
engine number G29345 = G.M.C. 248 c.i.d. engine
If this truck was a 1950 it would have been a Maple leaf 3 ton, but the Maple leaf designation stopped in 1950. The truck should have turn down door handles and vent windows, hope that helps.
