I can't find any manufacturer markings on it, other than the original owners self-applied brass tag.
I paid $25 for it, so hoping I didn't get burned too bad, John K.
I have to do some tinkering, but I think one of those keys will work.
The guy wouldn't let me have all the contents for that price....approximately 20 taps, a Bog manufacturing piston ring groove cleaner, several large drill bits, some huge sockets, a Blackhawk t-bar missing the drive slider, vacuum gauge in box, etc.
I plan on storing all my Coleman lantern cleaning and rehab tools in it, along with extra parts.
