Description
Huber Industries Type 249 Model A Adjustable Mount for N-9 Aircraft Gunsight – Early P-51D Mustang
Item Overview
This Huber Industries Type 249 Model A adjustable mount was manufactured to support and align the N-9 optical aircraft gunsight. Its black baseplate identifies the assembly as “MOUNT, ADJUSTABLE,” followed by the type, model, sight application, manufacturer, and Cincinnati, Ohio, location. The mount held the sight in the pilot’s forward field of view and provided the controlled adjustment needed during installation and gun-sight alignment. The U.S. Army Air Forces documented the N-9 on earlier North American P-51D Mustangs. Later P-51D aircraft used the K-14 or K-14A computing sight. This listing is for the mechanical mounting assembly only.
Identification and Features
The original black identification plate provides clear maker and application information. Its nomenclature distinguishes the assembly as the adjustable mount rather than the optical gunsight. The assembly retains its baseplate, mounting plates, and adjustment hardware.
- Marked nomenclature: MOUNT, ADJUSTABLE
- Mount designation: Type 249 Model A
- Gunsight application: N-9 sight
- Documented aircraft application: Early P-51D Mustang
- Manufacturer: Huber Industries Inc.
- Manufacturing location: Cincinnati, Ohio, U.S.A.
- Included: Mounting plates and adjustment hardware shown
- Not included: N-9 optical gunsight
Historical Background
The N-9 was a conventional optical aircraft gunsight used before computing sights became standard on later P-51D Mustangs. It presented the pilot with an illuminated aiming reference while looking forward through the reflector glass. For accurate fire, the mounted sight had to be aligned with the aircraft’s fixed-gun harmonization pattern. The Type 249 Model A supplied the mechanical support and adjustment needed for that alignment. The P-51 Mustang was developed by North American Aviation in 1940 and became one of the best-known American fighters of World War II. The P-51D added a bubble canopy, improved pilot visibility, and an armament of six wing-mounted .50-cal. machine guns. P-51Ds entered combat in large numbers during 1944 and served as long-range bomber escorts, air-combat fighters, and fighter-bombers. The August 1945 Pilot Training Manual for the Mustang states that earlier P-51D aircraft carried the N-9, while later aircraft used the K-14 or K-14A. This mount therefore belongs to the early P-51D gunsight configuration used during the transition from a fixed optical sight to a lead-computing sight. The Mustang later served in the Korean War.
Condition
This example retains its black identification baseplate with the Type 249 Model A, N-9 sight application, Huber Industries name, and Cincinnati location clearly readable. The mechanical mounting plates and adjustment hardware shown in the photographs remain attached. The painted and exposed metal surfaces show age-related handling and storage wear.
Ideal For
The clearly marked baseplate and documented early P-51D application make this mount a strong display and research component. It can add an authentic mechanical element to an N-9 gunsight exhibit, an early Mustang cockpit display, or a study of World War II aircraft gun alignment.
