I called and left a message about 2hrs after the ad was placed, but he didn't get back to me until last night. I drove down and picked it up this morning.
The guy is a VW mechanic at a dealership that provides tools for their techs. It's a new building with built-in boxes. His home box is a Taskmaster top and bottom with a Husky mid box. He already blew out the bottom drawer overloading it. I still don't understand why he sold the Huot.

But hey, I'll take it.
I was hoping that I could knock out the dents from the inside, but the box is double walled. I'd have to break the welds to get to them and it isn't worth the effort. The drawers all slide well, but the dried grease makes it hard. A good cleaning and some Door-Ease will fix that easily. The same with the casters. The paint is a light hammered blue, with gray/silver hammered drawers. Someday I may repaint it. I'll have to have a new key made, but it can wait for now.
I didn't bother to haggle over the price. It's heavy built and worth the $50, even to a cheapskate like me. It's the perfect hight to roll under the benches I never seem to get around to building.
I've spent some time searching for a model number for this box, but no luck. There are no markings, and an internet search still hasn't come up with anything. The closest I found was on this site for a model #201 bottom box, but that has a different drawer configuration. Because of the color, I'm thinking that it was made in the 70's, but that's just a guess.
The first three pics are from the listing. The others are in my shop. (including my sister's dog checking it out and giving me "that look" like I'm an idiot for bringing another piece of junk in the house. Dogs have no appreciation for quality.

)
Any help on age or model number would be appreciated.
