Their smaller belt sander looks a little like a Ryobi, but Ryobi doesn't make anything over 5.3amps by the look of it. A couple of years back when I was doing some research on them, I'm pretty sure that "Bosch" came up as a manufacturer of the larger units, probably yours(no jokes about having a large unit, please).
