Simplex also made "Marine" versions of these extinguishers for boats. These had a sprung-loaded T-handle through the cap. This shaft of the handle bore down on the cap of the bottle and prevented it from splashing about prematurely (I think that's the term). The instructions reminded users that the handle had to be pushed down and turned anti-clockwise, then turn the extinguisher upside down.

The "Marine" type may have been the version fitted to trucks.
