I have a brand new Mac Tools MB1350 Macsimizer Tool Box for sale. Below is toolbox description from website. So I bought the bottom box for approximately 1/3 of what they normally sell for, $500!
The box would clean up just fine, and the drawer slides just needed to be cleaned, de-greased and then properly lubed. However, I was able to recognize that there were no dents or dings, nor any real defects. In addition many of the drawers were sticky and did not slide open freely. It was extremely dirty, from 20+ years of use. I checked out the box and it was in very good condition. These older boxes are 50' or so in length, boxes are customarily much larger, now. The Snap On dealer really didn't want to take the lower box into his inventory, due to its age and size. The old one was a MAC 1700B, like the one pictured below. A local mechanic was purchasing a new bottom box, and trading in his old one. So a few years ago I was presented with an opportunity to purchase a vintage MAC tool box.
