Original Item. Only One Available. The .50 cal T&E traverse and elevation mechanism is used to engage preselected targeted areas at night or during limited visibility conditions. These readings are measured from the traversing bar on the M3 tripod and the T&E mechanism.

To obtain accurate readings, the T&E has to be zeroed, with all measurements recorded in mils. The T&E mechanism consists of a traversing hand wheel, locking nut, scale, and yoke. The T&E is attached to the traversing bar of the M3 tripod.

This example is stamped on the side 53711 ASSY 5830128 MER 97001. It’s stamped into the metal 6195550. It is in good shape but is applied with cosmoline in some places. This is a difficult item to find. Ready for further research and display.

The M3 tripod is a weapon mount used on the M2HB Browning machine gun and the Mk 19 grenade launcher. The M3 tripod has a total weight of 20 kilograms (44 pounds). The M205 tripod, formerly the XM205, is intended to replace it.

Specifications
The M3 tripod is designed for portability but due to its solid metal construction weighs in at 20kg (44lb). When fully extended it measures 14"(35.56cm)high by 61 1/2"(156.21cm)wide by 76"(193.04cm)long. When collapsed it measures 48 1/2"x 8"x 7" (123.19cm x 20.32cm x17.78cm). It has a total traverse range of 425mils with the T&E mechanism (traversing and elevating mechanism) and 6,400 mils without it. The maximum elevation is 100mils and the maximum depression is 250mils with the T&E mechanism. Without the T&E Mechanism, the tripod can angle the weapon at 285 mils up or 335 mils down from zero

The Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft.

The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NATO countries and has been used by many other countries as well. U.S. forces have used the M2 longer than any other firearm except the .45 ACP M1911 pistol, which was also designed by John Browning.

The current M2HB (heavy barrel) is manufactured in the U.S. by General Dynamics Ohio Ordnance Works, and U.S. Ordnance for use by the U.S. government, and for allies via Foreign Military Sales, as well as by foreign manufacturers such as FN Herstal.
