The Jennings rifles were the successor to the Hunt Repeating Rifle and were manufactured by Robbins & Lawrence in Windsor, Vermont, c. 1850-51. It is believed that less then 1,000 of all variations were made despite an original order for 5,000. This particular variation is a First Model breech loading, single shot rifle, and this example is pictured on page 13 of "Volcanic Firearms: Predecessor to the Winchester Rifle" by Edmund E. Lewis and Stephen W. Rutter and listed as from the latter's collection. The rifle utilizes a "Rocket Ball" cartridge which is loaded through the right side of the frame. A ring trigger operates the breech and automatic pill primer device which is no longer used on this version as it has been adapted for use with percussion caps by fitting a nipple. The magazine tube was made smaller in diameter and is used for carrying the cleaning rod. The Rocket Ball's insufficient power made it impractical for hunting or military use which led to its lack of success and the small number produced. The action, trigger guard, and buttplate have light floral scroll engraving. The left side of the receiver is marked "ROBBINS & LAWRENCE/MAKERS/WINDSOR VT." and "PATENT 1849/C.P. DIXON AGENT/NEW YORK." "341" is marked on the lower tang, and the pictures in the book noted above indicate matching serial numbers are also on the internal components. It has a brass blade front sight, notch rear sight, brass tipped wooden cleaning rod, and a straight grip stock with an iron buttplate.
