The VIN 9JKD14760 is almost correct for a 51 4400 1 1/2 ton 161 wheel base. The J is the correct year code for 1951 in light and medium trucks but it is a U for heavy duty trucks. The K is correct for 4400 for every year 48-51. The 9 is correct for the Norwood OH assembly plant. The D is the month code for April. I think the U stamped on the plate may look like a J. So I guess April 1951 4400 Norwood. Try
