From the Universal archives:
If I'm not mistaken, the Reaver version that crashed at Mr. Universe's place, was the only physical model ever built. that version had all the markings obscured to hide itself when escaping Miranda. That's why Inara was repainting it at the end of SERENITY,I still wonder why they didn't paint the logo on there, seems like an obvious detail to miss.
