Super Tootsietoy U-Haul Truck

I picked up this Super Tootsietoy U-Haul Truck. No. 2927-129, 8 3/4". It's bigger than most of the Tootsie's I've seen. If anyone knows how long the Super Tootsietoys were made and when? Know of any other vehicles, besides the Ford cab in the series? Does anybody know any other types of rear bed loads besides this and the bucket truck? Also the years made? I'm guessing mid-late '60s. Also give me your best guess what year what year Ford Truck this is supposed to be? That will help me better nail down a year. I'm not going to give my guess. I appreciate any info.
