Terry,

You ask, "Why would anyone want one that was rust colored?"
If you look further you'll see other discrepancies.
There has never been a PCF with rust stains. All the PCFs were aluminum. Rust stains are from steel hulled ships like DDs, DEs, freighters and the like. A rust stain would take any semblence of authenticity away from a model PCF, like that particular model had any to begin with. It's still missing necessary hardware. It's still just a lousy model for a lot of money.
