Though marked as a 30 Magnum Mark IV, the configuration is similar to a Mark III 22 LR, possibly an early stage prototype using available parts. The Mark III was introduced in 1986. Adjustable pin and two leaf sights with protectors, ribbed forearm, fixed metal stock, magazine well grip with insert, and frame marked "INGRAM MK I V/ 30 MAGNUM" and "00002" on the right side, "LAS VEGAS, NV/ U.S.A." on the left side. A Tasco scope is mounted to the left side. With documents relating to the Mark III-V arms and a Model 6 magazine pouch dated 1950. Magazine not included.

Excellent, with 95% of the blue finish, showing some rough machining and welds under the finish, along with some mild handling marks overall. Optics are fair.
