The cab pinstripe was optional - I had a 1948 panel truck and it had no pinstripe. Jim Carter, I think, made the comment that the pinstripe was put on if the truck-color (or, if a truck with pinstripe) was ordered from the factory. I think he also suggested that sometimes the pinstriper (at the factory) would randomly put a pinstripe on a standard truck as it passed along on the assembly line (out of boredom, or having spare time and a wet brush with the right pinstripe color)?

Regarding pinstripes on wheels: some documents state they were only applied to 16" wheels? Some people say they were only painted on wheels that were painted body color? I recall seeing documents for certain years that said that two stripes (instead of three) were painted on some of the larger truck wheels (I'll look tonight)? No one really knows, unless you find a living pinstriper.
