Obviously someone has decided to dispose of a small and nicely inclusive collection of classic vintage pistols. I suspect the estimates are 'come-and-buy me's' and it will be interesting to see what these eventually go for.
One of the 'Pope Bro's Rifle' air pistols is actually a Eureka, with a probable replacement cocking rod knob. The real Pope is interesting, as it is an example of the rarer serial-numbered version.
