Quackenbush rifle
The Quackenbush rifle, invented by industrialist Henry M. Quackenbush, is a clever but cheaply made "Boys' rifle" sold in large numbers in the 1893-1920 period, along with several models of air guns.
They came with either a fixed wire stock or one that slid forward for use as a "bicycle rifle" nearly identical with the stock later used on the USAF M4 survival rifle.
There were eleven models of the air rifle. The last were produced in the late 1940s.
The Quackenbush rifles are fairly desirable collector items and sell for several hundred dollars depending on the exact model and the condition.
