I am the 2nd owner of this keyboard.  It has only seen home studio use, it has literally only moved since 1980 when going to the shop every several years and when I bought it from him.  From the front and sides, it appears Minty.  The back has a bit of mottling in the finish. I’ve had the capacitors replaced as shown in one of the photos.  Fully functional with the last servicing just a couple years ago, including the aftertouch working well.  It’s been 8-10 years since the sliders were cleaned out in detail however, so there can be some scratch when you slide them (completely standard on all ARPs, and note all the large late-period ARP slider caps are present).

If professional packing and insured shipping is more that $50 less than the purchase price, I’ll refund the difference, but don’t count on it.

Finally, if you’ve made it this far, even if not buying a Quadra, please read the (two-part!) seminal Quadra overviews by Gordon Reid in Sound On Sound some number of years back. The only thing I disagree with is that the chassis doesn’t flex at all when lifting it.
