SN10487 sold on November 4th on eBay for $2,400
The owner informs the machine is headed to Arkansas, though to where he did not say. The unit does work, although apparantly the TV won't turn on. The boards in the set do warm up though so it's probably something minor for a fix.
This machine was taken out of service in 1980 (no doubt due to rotten gameplay) and sat in the seller's shop ever since then.
Amusingly this very own website was used in the auction as a resource for prospective buyers. Always happy to assist the community!
UPDATE: The new owner has sent in a number of new pictures of this machine, click the thumbnails at the bottom of this page to see the large (half a megabyte) versions.
