Wow!!! The Photo Source in Sacramento listed #9-542 (1959), which was in really rough shape, for $500. eBay shows it appeared at 2:01 pm Pacific time today, and it sold 34 minutes later (!!!) at 2:35 pm. Looks like someone got a good restoration project.
What caught my eye with that one is that its spec indicated the early focal length and ratio of 42.4 inches (1077mm) at f/12.1. To my knowledge, Questar transitioned to indicating 45.5 inches at f/13 on the bottom of the barrel sometime in early to mid 1960.
