anything is possible, such as doors swapped to wing/non-wing, etc.
however, the '52 standard-cab b-3-c my dad purchased in 1983 has vent windows. nothing to indicate they weren't original to the truck when he purchased it. truck originally came from north carolina. note the red under the door card matches the red of the cab roof, while the remainder of the truck (dash, lower door & exterior) was painted maroon/burgundy.
edit: in looking at Bunn's book, my '52 is a deluxe cab rather than a standard cab, as it has electric wipers, the dome light, and dual wing vent windows. so, merle was correct. according to Bunn, the deluxe cab didn't come with cab corner windows. a custom cab would also have the driver armrest, cab corner (quarter) windows, and dual sun visors, too.
also, the standard/deluxe/custom "standards" changed from 48-50 to 51-53, with some gains and losses depending on which level was chosen, ie, cab corner windows for deluxe and custom 48-50, but only for custom 51-53, and dome light/electric wipers only for custom 48-50, yet for both deluxe and custom 51-53. etc.
