This Jennings rifle was manufactured in 1852 by Robbins and Lawrence in Windsor, Vermont, as a muzzleloader. These rifles were manufactured using modified components from the unsuccessful Jennings breechloading and repeating rifles. In place of the magazine tube, a smaller tube under the barrel holds the ramrod. The small door used for loading the breechloading rifles remains on the right side, but opening the door reveals a breech plug instead of an open chamber. The rifled barrel has a small blade front sight and a small notch rear sight on a larger dovetailed base. The breech end of the barrel and the lower tang have "7V," and the trigger guard has "7." The action and furniture have simple scroll engraving, and the rifle has a "squashed" S-shaped trigger guard rather than the large trigger guard for the sliding trigger of the earlier models. The stock has an engraved silver plaque on the right side.

Very good with dark brown patina and mild oxidation, distinct engraving, and moderate overall wear. The stock is fine and has strong original finish, some dings and scratches, and mild wear mainly at the edges. Mechanically fine.
