Welcome to in the present day’s Photo of the Day! Within the late Nineteen Twenties, the Italian army sought to supply infantry with an natural grenade-launching functionality. Their unconventional resolution was the Tromboncino M28 – a grenade launcher built-in into the Carcano M91TS carbine. The Tromboncino utilized a novel “shared bolt” design. The carbine’s bolt may very well be eliminated and inserted right into a separate receiver mounted on the rifle’s proper aspect. This second receiver terminated in a grenade launching cup as an alternative of a barrel. Fairly than make use of blanks, the Tromboncino launched normal 6.5x52mm Carcano rifle ammunition to propel its grenades. A bullet lure on the muzzle allowed fired bullets to obturate gases, venting them out rear ports to launch the 38.5mm projectile from the cup. Whereas ingenious in conception, the Tromboncino suffered from anemic grenade efficiency. Designed as an offensive weapon for shock assaults, its low-explosive grenades lacked adequate fragmentation results for fight use. After simply 6 years of service, the difficult and costly Tromboncino was declared out of date in 1934. It was changed by standard mortars just like the Brixia Mannequin 35 for infantry fireplace assist. Although revolutionary, the Tromboncino’s flawed grenade ammunition doomed this ahead-of-its-time weapon system.
“Developed within the late 1920, the Tromboncino M28 works on the identical mechanical rules as a typical “cup” launcher (a discharged cartridge provides propellant gasoline to a projectile resting in a chamber), however with a twist; as an alternative of merely attaching a grenade chamber to the muzzle of a rifle, the M28 makes use of a devoted blank-only receiver with mounted grenade chamber, which is then affixed to the correct aspect of a whole infantry rifle. This mix was solely in use from about 1928 to 1934, the place it was retired in favor of a devoted gentle infantry mortar; most had been scrapped with the bottom firearms returned to straightforward configuration. The set off mechanism is interconnected to each the rifle and the launcher, and so as to save weight and stop inadvertent discharge each share a single bolt. “
