M73 Machine Gun
The M73 and M219 are 7.62 mm NATO caliber machine guns designed for tank use. NATO no longer uses them, but they were used on the M48 Patton and M60 Patton MBT series (including the M728 Combat Engineer Vehicle), as well as the MBT-70 prototype vehicles, and on the M551 Sheridan Armored Reconnaissance / Airborne Assault Vehicle (AR/AAV). They were also used in a twin mount in the turret of the V-100 Commando (M706) light armored car during the Vietnam War. Also used on the M60A1 Tank. Design and development Designed primarily as a coaxial machine gun by the Rock Island Arsenal and produced by General Electric, the M73 was developed as a replacement for the M1919A4E1, M1919A5, and M37 machine guns that continued to serve in the immediate post–World War II environment. The ''Machine Gun, 7.62-MM, M73'' was officially adopted in 1959. It is an air-cooled, recoil-operated machine gun, but also using cartridge gases to boost recoil. Though designed as a simplified alternativ ...

M-73 (Michigan Highway)
M-73 is a north–south state trunkline highway in the Upper Peninsula of the US state of Michigan. It connects with US Highway 2 (US 2) and Highway 55 (WIS 55) at the state line near Iron River.

BMW M73
The BMW M73 is a naturally-aspirated, SOHC, V12 petrol engine which replaced the BMW M70 and was produced from 1993 to 2002. It was used in the BMW E38 7 Series, E31 8 Series and Rolls-Royce Silver Seraph. Design Compared with its M70 predecessor, the M73 features an updated roller-rocker valve-train and an increased displacement, due to a bore increase of ending with a cylinder bore of 85mm and a stroke increase of to have a final piston stroke of 79mm. While most other engines in the BMW range had switched to dual overhead camshafts with four valves per cylinder, the M73 used a single overhead camshaft and with two valves per cylinder. However, BMW engineers did create a prototype four-valve per cylinder V12, called the M72, which developed and of torque. However, this 48-valve engine did not fulfill the comfort demands of the large sedan class in all respects and, as a result, did not go into production. Some versions of the engine have two separate Bosch Motronic e ...
