My main box is Waterloo, top,bottom, and 2 side hangers One older cman upper which is going to one of my sons next week. ! home made bottom roll around and several various smaller boxes SK, Kennedy Snap on and some unmarked ones. Not overly impressed with the Waterloo. I've moved it several times and the drawers are not taking the moves very well.

At work, Snapon top and bottom, 1980s, bought them used when wanting ball bearing drawers.  Drawers are still too shallow.  At home, a 1950s Craftsman top and bottom, 3 drawers each, from a relatives auction.  Plus a Craftsman 26 inch bottom, and a Blackhawk top chest 10 drawer, probably late 60s, as I bought it used in 76.  Small hand carry boxes, Craftsman, S&K, Park, and a dozen others. 

I have a Montezuma roller and a carry, got them for Christmas a while back, serves me just fine.

yesterday I was talking to a guy and we were talking about tools, I remembered this subject and told him
about it, then asked him what brand of tool box he uses,  his answer was very quick, "OP"  yes, he was serious,

OP = other peoples.
