Mod 3 was, for one gun, lengthened to 40 calibers and was removed from service prior to the start of World War I. Mod 4 was, also for one gun only, different from other Mods in having a ring shrunk onto the breech end, tapering the breech, and with a small balancing hoop screwed onto the front chase hoop.

Mods 2 through 9 were for minor differences primarily for testing different mounting techniques. Mod 10 was for one gun cut down to 23 calibers and used for experimental work with high-explosive shells. Mod 11 was a Mod 4 gun, No. 72, with an

All Mark 5 guns were subsequently removed from service by 1908, lengthened to 45 calibers by adding a new liner and rehooped to the muzzle, redesignated as Mod 1 and then placed into reserve.

The Mark 4s were Nos. 22 – 32, 38 – 50, and 52 – 83.

This allowed these guns to be screwed

The Mark 5, Nos. 84 – 107, was a new 40 caliber design intended for armored cruisers and battleship secondaries and constructed of tube, jacket, three hoops and one locking ring. This gun had a muzzle bell. Unfortunately, the Mark 5 proved to be unable to handle the transition from black powder to
