DWARF..?? What the...?

[someone else]

So, I found an interesting little amp....
It's the 'cutest lil thang'
It is called a 'Dwarf' Anybody ever heard of them ?
It was made, I think, till about '74 or '75
A competitor to the Pignose, or Mike Mathews freedom amps, which were both battery operated.
The distinction of the dwarf, however, is that you can also plug it in.
It was a hardwood case, (mine is oak) with dovetail corners, and I'm not sure if there was more than one model,??
Mine is 5 watts, has a line out, and speaker out, and .....get this..... an overdrive circuit...!!!
It runs on 18 volts, 12 C cells, or plug in, and has a 5" speaker.
The sound, for its size, is pretty impressive... anybody got any more info on this lil thing I'd be most happy to accept the help.
