H.I.
To answer your question, officially no Chevy did not have a longbed 1/2-ton in 47 thru 55-1st (Advance Design) and yes GMC did. The 1/2-ton 3100 series pickup had a 6 1/2' bed and 116" wheelbase. The 3/4-ton Chevy and longbed 1/2-ton GMC had a bed 7'-3" long with 3 stack pockets, the first 2 ahead of the fender until 54 when it grew a few inches but still was not a full 8' long until the "new" 55-2nd series. Starting then with the Task Force trucks Chevy had a 1/2-ton longbed. Of course anything is possible and as some have said "a lot can happen in 50+ years". Maybe it's a Chevy cab on a GMC frame, etc..... smile
