Looks like they were making another Nomad. But families wanted to have rear seat access separate from the front seat, so the two-door wagons always got short shrift.
Zombie families, maybe. That was a hearse conversion for the Portuguese market. It also has a Stovebolt 6:
Now that I gandered at the H.A.M.B. webpage, I can see what they did, which made the rear look like a '60, but on a '59 body. Totally impractical, also, for families and grocery-getting.
Opening the link, there are TWO different '60 Chevy wagons here, both converted from Impala 4-door hardtops. Frankly, I prefer the OTHER one, with the more conventional liftgate and back window.
Have not seen the link for the 60's you are talking about KK. As for the 59 I originally posted, the picture with no info I found online dating 2007 and it was full size. Clearly it was not a hearse yet was a 4 door family wagon. Why(?) the pic shows me a tiny picture? Was is a survived prototype? Was it a custom job?.... there was no info, the link that came with the pic was dead. EDIT....Cool, hope this pic turns up full size. Hard to tell IMO but maybe it is a hearse as Hans pointed out,,,,,, none the less the roof lines, glass lines/rear doors, it's a lot sharper than a USA production 59. Agree also on that other 60 in the Jelop-Journal
Evidently, like Krash wrote, this was originally a four-door hardtop converted over into a wagon. If both year's sheetmetal lined up, then it was a '60 with a '59 front clip
