It's not a Smith & Wesson.
It's a Harrington & Richardson that is chambered for a cartridge known as the .32 Smith & Wesson.
.32 S&W is an old, originally black powder cartridge that was once exceptionally popular in these small "belly" or "hide out" guns, but which has slowly lost steam over the years.
It is still loaded, but it's getting a lot more expensive and a lot more difficult to find.
