Kirk Gun Co. was a trademark of Farwell, Ozmun, and Kirk. Inc, a hardware dealer in St. Paul, Minnesota. They made guns from roughly 1911 to just after World War II, best as I can determine. The weapon is a typical "hardware store gun", an it's intrinsic value is not high, made even less so by being a single shot. To collectors, though, it might be an addition to their collection that's they'd happily pay some bucks for.
