Stepside special editions?

[l79m20]

Just bought this 71 stepside from the original owners wife. It has all original paint that has patinad all over. Its an all blue truck but has some white pin striping around the bed fender lines, cab lines and on the front fender. Also has a pair of smaller stripes on the hood. Granted most of these have worn about all the way off but you can see where they were. I know the squarebody trucks had the sport truck in the mid 70's that just had a stripe package added. I've done some looking around here and the rest of the internet and I don't find any ads or pictures for this era of truck having that type of an "edition". I'll post a pic as soon as I can. Any info would be great.
