These are one-of-a-kind prototype rifles that Eugene (Gene) Reising prepared for possible production with any of the manufacturers (H&R, Savage, Remington, etc) back in the 60’s. Gene passed in 1967 so these never made it to production. No known production. Not so common configuration; slide pump action with a 3-round clip. Virtually twins of each other with different calibers intended for different manufacturers. One calibered at .300 Savage and the other at .35 Remington.
