I recently acquired this H&R Hammerless Bicycle Gun. In excellent condition with a blued finish (rather than the more common nickel finish), MOP grips and in .32 caliber it dates to 1914-15. These small frame bicycle guns were only made from 1899 to 1920. Intended for bicyclists to dispatch mad dogs that seem to have wandered the US countryside unabated at the time. In my experience, when riding a bicycle most dogs that I encountered seemed mad, perhaps they were jealous of my bipedal ability (or lack there of).
