1978 Craftsman bottom. Had to replace casters, also made a heavy duty frame out of angle iron. I was rolling the box a few miles a day back then.
1982 Mac Top. Traded junk Kmart set of golf clubs. I won that deal. Made my living working out of these until 1992.
2005 Excel generic box, but has nice ball bearing drawers. Wanted storage under my bench and this fit perfectly. Found on Craigslist for $70 new, but with minor damage on base that was easily repairable.
