Now, I have to admit, the PCC doesn't appear in any of the photos on the Facebook post, so I can't be certain it's included in the auction. But it seems likely. Aumann says they will add a full listing to their website soon, so that should answer any questions. If car 1150 goes up for auction, hopefully it finds a good home.
On a totally unrelated subject, I've removed the above car, Companhia Municipal de Transportes Coletivos 1791, from the PNAERC roster. It's an ex-Third Avenue Railway System "Huffliner" built by TARS in 1938 and sold to the Sao Paolo, Brazil, system in 1947. Until sometime in the last couple of decades it was on display under a shelter at the Clube Esportivo Nautico de Guarapiranga, located near Sao Paolo, but I cannot find any evidence that it's still there despite the club being very well documented in online photographs. Until I can find some evidence that the car still exists, it's off the list.
