Good news Ronman!

Your stamped numbers on that plate decode as:
14 = Built at the Baltimore, MD Assembly Plant
FS = 1948 Model 3800 (1 Ton)
K = Month of Assembly - November 1948
3810 = Serial Number (All plants started serial numbers at 1001 each year, so yours would be the 2810th built at the Baltimore plant)
The printed decal portion isn't really relevant for identifying your truck as the stamped characters are what counts.

NOTE: All this info is included in that snapshot Kevin attached above.
