Salvaged from the Baltimore, Maryland, fireboat, "Mayor J. Harold Grady", this high-capacity water cannon (also known as a fire monitor, deluge gun, or deck gun) was in use from 1961 to 2007. With an output of 3000 gpm (Gallons per Minute) at 300 Psi, this cannon can project water over great distances. Manufactured by A. J. Morse and Son Inc, this model was dubbed "The Invincible Nozzle" due to its high-quality construction. This model was considered to have a superior design and functionality than other water cannons of the time. As a result, much of Baltimore's fireboat fleet were outfitted with this model of monitor.
Coated in a white marine grade paint, this cannon is made entirely of brass components, with exception of the steel fitting at the base. The tapered smooth-bore nozzle measures approximately 12" long with a diameter of 6 1/2". The 49" long barrel extends from a geared fitting attached to the yoke-like split piping of the base. A 24 1/2" handwheel that operates a worm gear is mounted and extends from the crook of the yoke. When turned, the gear on the handwheel meshes with the geared fitting at the base of the barrel, raising or lowering the nozzle on a vertical axis. Below the split piping, an additional 13 1/2" handwheel with a worm gear is mounted. When turned, the gear meshes with a built-in gear on the base, moving the nozzle along a horizontal axis. This cannon has a 12" diameter base fitting with 12 mounting holes measuring 3/4".
We currently have 2 of these cannons in stock. Each has slight variance in condition. Both have flaked paint and show wear and tear consistent with use over time in a harsh nautical environment. One has a bent upper handwheel shaft and does not have the "Invincible Nozzle" plaque. The other is in excellent shape and does have the "Invincible Nozzle" plaque.
