I remember at least a decade back there was a C-131 for sale on ebay still in full US Navy regalia. It looked more or less complete, but was not airworthy. The seller made sure to mention that the aircraft had been inspected by Kelowna Flightcraft (who, as I understand it, own the type certificate) and found to be "restorable to Part 121 standard". However, naturally, the cost of such a restoration was not mentioned. I haven't seen the aircraft since, so I assume it's sitting derelict somewhere.
Sure is a shame about the crash, I believe that was the last airworthy C-131 in the world.
