Fewer than 600 total repeating rifles based on Orvill M. Robinson were manufactured in the early 1870s. There were two major variations based on the action design, but many of these Type II rifles also show considerable variation between rifle to rifle making each an interesting example of scarce early cartridge repeater. They were only manufactured c. 1872-1874. This design is based on U.S. patent number 125,988 "Improvement in Breech-Loading Firearms", granted April 23, 1872 to Orvill M. Robinson of Upper Jay, New York. A.S. Babbitt of Plattsburgh, New York, may have manufactured these arms while the Adirondack Firearms Company of Plattsburgh, New York, was formed to market them. Winchester purchased the company in 1874 and did not use the design. This rifle is a later variant and features a hammer at the rear, a hand-operated pivoting rear breechblock connected by a link to a sliding breech bolt, tube magazine, and a built in cartridge elevator. A sliding lever on the left limits the length of cartridges that will feed into the cartridge elevator allowing the use of different length .44 rimfire cartridges. The barrel features traditional blade front and sporting rear sights (rear elevator absent). The bottom of the frame at the front is marked "30." The bolt is marked "ROBINSON'S PAT. APR. 23D 72./MF'D BY ADIRONDACK FIRE ARMS Co./PLATTSBURGH, N.Y." The rifle has a smooth walnut buttstock with a crescent brass buttplate.

Good. The iron features dark brown patina overall and some mild pitting. The brass has a deep aged patina. The refinished stock is fair and has some repairs and loose fit in the wrist. The mainspring will slip off the hammer if the tension screw is loose, but if it is tighter, the hammer is locked in place. With the screw just right, it will mechanically function. This is a very rare and interesting piece of American firearms design history and early Winchester history. The company purchased some of their potential competitors early on to solidify their hold on the repeating rifle market.
