I have just acquired this monster and I plan on restoring it. Does anyone here know where to get info on this kind of stuff? I have Googled the heck out of this thing but there is very limited info available. I guess they went out of business after WWII. This thing is crazy heavy. I bent my 1.5 ton cherry picker with the boom as short as I could make it.

 

nice box, shouldn't have to worry about a crackhead wandering off with it.
