There are a LOT of people that collect Rugers.
Go look around and try to buy a NIB Hawkeye pistol. Why would anybody want one of those single shot funny looking things anyway, right? Wait until you see what people are paying for them!
And unconverted Old Models are worth quite a bit today. As are original Flat Tops. And Speed Sixes. Especially the 9mms. And people spend truly vast amounts of money on custom Ruger single actions. Bowen and Clements and others have a waiting list and make their living satisfying those people.
