This is a vintage Buddy L Big Mack Heavy Duty Hydraulic Dump Truck. I believe it is #5812 and is the 4 wheel version. It is made of pressed steel and was manufactured in the 1970s. It measures approximately 20 inches in length and 10.5 inches tall.Condition: The overall condition is good. The wheels all roll fine. The hydraulic dump operates. The windshield and side windows are intact. The paint and decals are very good with the exception of some unidentifiable gray residue that's on f...ront grill and bumper (see photo 3) and the front middle of the bed (see photo 12). I've been able to pick some of it off and believe more if not all of it can be picked off, but it is time consuming and I'm not positive it will all come off. The lever and catch to hold the dump bed down are missing. Therefore, someone has rigged a wire system to hold it down (see photos 10 & 11). For full information on condition, please see the photographs.I do my best to identify the truck number and time of manufacture, but I cannot guarantee that they are correct.Additionally, I do not have the level of expertise to determine if an item is all original or has been restored/repainted. Please make your own determination based on the description & photographs and feel free to ask questions.This item is from my late father's collection. He had hundreds of these types of old toy trucks. They include manufacturers Structo, Buddy L, NY-LINT, Model Toys, Ertl, Tonka, Hubley, Smith Miller, Wyandotte, and more. Everything from fire trucks to construction trucks to delivery trucks. I'll be selling all of them as time allows.
