Vintage Koestler Harmophone Electric Organ 1960's

Here's a really cool suitcase electric pump organ from West Germany, made in the 1960's. This thing is pretty loud, considering the size of it. Aesthetically, it's in pretty good shape. It has wear from the years, handle on the suitcase had been broken previously but is now fixed, though there is a chip missing out of it (see pictures). Everything sounds great on it and works as it should. Also, you can take the top off and I think that it makes it pretty cool looking.
