bayonet socket

Unlike bayonet sockets, three-way and regular lamps are interchangeable, although the low filament or low setting doesn't work if mismatched.

The wheel-lug wrench served as a handle (also for the jack) and the jack shaft with bayonet-coupling pins could be inserted through a small hole in the grille to engage a bayonet socket on the forward end of the engine crankshaft.

It was rechambered to the standard German 7.92x57mm IS cartridge with a fully enclosed flush magazine, the bolt handle was made angled, the bayonet socket was changed to accept German bayonets and some alterations was made to the sling mount.

The distinctive features of the apparatus consisted of 'a section of a cylinder, which is fitted to the barrel of a musket by a bayonet socket; a rocket with a line attached to its stick is so placed in it that its priming receives fire immediately from the barrel'.
