You have the only one. No others were ever made. This is the ultimate rare truck.

http://www.nedirtbikes.com/forum/smiles/bsflag.gif[/img] aside - hard to say. There are no production numbers available for '54 that I know of. I have TOTAL production for ALL trucks, but not for any particular size style etc.
In general, GMC made 10-15,000 3/4 tons per year in the early and mid 50s from what I can tell. Of those, maybe 2000 were from Oakland and similar amounts from the St. Louis plant.
Assuming that 25% of the trucks survived, 2,000 Oakland trucks become 500 or so that might still be around.
It's an impossible number to develop but this is an "edumacated guess".
