T-24 Indicator Azimuth Assembly with Instrument Light – Shipped in the Original Metal Barrel
P/N 7537555 – FSN 1290-753-7555
Add a scarce and highly specialized piece of U.S. armored vehicle fire-control equipment to your collection with this T-24 Indicator Azimuth Assembly with Instrument Light. Identified by P/N 7537555 and FSN 1290-753-7555, this is an original military azimuth indicator assembly offered exactly as serious collectors like to find them—shipped with the original metal barrel.
This is the kind of item that rarely survives with its packaging, and even more rarely with the original instrument light assembly still accompanying it. For collectors of armored vehicle optics, fire-control hardware, and Cold War-era tank equipment, this is a standout piece with real display appeal and strong technical-history value.
The T-24 / M31 Azimuth Indicator
The T-24 designation is associated with the M31 mechanical azimuth indicator, a compact fire-control instrument used to help the gunner track and reference turret direction. In practical terms, an azimuth indicator gave crews a quick visual reference for turret bearing, making it useful for laying, correcting, and reestablishing direction during gunnery work. In armored vehicles that carried both direct-fire and indirect-fire related sighting equipment, the azimuth indicator formed part of the wider aiming and fire-control layout.
This instrument family is documented as the M31 (T24) and appears in U.S. armored vehicle references as part of the gunner’s station on the M41 Walker Bulldog, where it sat among the rest of the gunner’s controls and sighting gear. That makes it an especially interesting component for collectors focused on postwar U.S. tanks, armored gunnery equipment, and mechanical fire-control systems.
About This T-24 Indicator Azimuth Assembly
This item is a complete Indicator Azimuth Assembly identified by P/N 7537555 and FSN 1290-753-7555.
Key features include:
Instrument Light Included
One of the most attractive details of this set is the inclusion of the instrument light. Fire-control and sighting instruments intended for vehicle use often required dedicated illumination for low-light or night operation, and having the light with the assembly gives the piece a more complete and correct appearance. For display purposes, it also adds visual interest and helps show how the indicator would have fit into a real turret environment.
Original Metal Barrel Packaging
This assembly is shipped in the original metal barrel, which is a major plus for collectors. Original packaging is often lost long before the instrument itself disappears, so surviving examples in their barrel are especially appealing. The barrel not only protects the indicator, but also reinforces the military character of the item and makes it an excellent presentation piece for display, storage, or collection.
Why This Piece Matters
The T-24 / M31 azimuth indicator is exactly the kind of specialized equipment that brings a restoration or display to life. It is a dedicated mechanical fire-control instrument tied to real light tank use, and it belongs to the same world as periscopes, quadrants, telescope mounts, and gunner’s controls.
That makes it especially desirable for:
