Newton Arms have revived the Leverbolt rifle that was invented by the famous gun and cartridge designer Charles Newton in 1929. The design borrows element from the Springfield, Lee Navy and the Winchester lever-action. By utilizing a lever the bolt can be cycled faster than a traditional straight pull bolt action.
According to my copy of Bolt Action Rifles (4th Edition), the story of the Leverbolt is a sad one. Charles designed the rifle after this business, Newton Buffolo Rifle Corporation, folded in early 1929. Unbeknown to him, and everyone else, the stock market would crash in October of that year heralding the beginning of the Great Depression.
Newton approached Marlin who agreed to limited production only if he could secure at least 500 orders. The cost was a $25 downpayment and an addional $35 on delivery. He failed to secure the neccessery orders and once the market crashed any chance of the rifle being manufactured was gone. Charles died a few years later aged 62.
Mehul, a moderator at nitroexpress.com and expert of the topic emailed me information about the Newton rifle:
For a straight pull action that is much sleeker than any of its competitors today (the Blaser R 93, Strasser RS 05 and the Heym SR 30 are three popular designs that come to mind) the Newton Leverbolt is especially interesting because it comes with a controlled feed and extraction system that would make it ideal for dangerous game. The speed of reloading and getting repeat shots off would also be ideal for an African rifle – with a 5 shot magazine in calibers from 375 H&H to 458 Lott this could be much better than anything else available today.
I am not sure of pricing or availability of the rifle at this time.
A big thanks to Mehul for the info.
