Marlin Levermatic

The Marlin Levermatic was a family of lever-action rifles created by Marlin Firearms in the 1950s. The Levermatic differed from the traditional lever-action rifles, such as the Marlin 39A, in that it employed a cam-and-roller system giving it an extremely smooth and short lever motion to reload a new cartridge.
This cam-and-roller system was originally invented by Kessler Arms Company for their "Lever-Matic" shotgun. Following Kessler's dissolution, Marlin licensed the idea and began producing rifles using a similar design.

Marlin had also planned to produce the Levermatic in .357 Magnum and .22 Remington Jet offered in the Marlin model 62. Both cartridges are related to the .256 Magnum which shared the same .357 Magnum parent case, but these options never materialized.
