Here is a useful ID link from Rob English's excellent old GMC website:

101 = 1/2 ton 100 series short bed
22 = 228 GMC engine
S = St. Louis assembly plant
6788 = sequence/production number = this code was on 1951 trucks of this size/model

This would have been a relatively early 1951 101-model - they might have still had the old doors/handles, or, the doors might have been replaced?

Thank you. This is the site I was looking at but was having trouble with the production number and which year it meant. I'll join that group also...
