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.

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. The original Mark 4 Mod 0 guns were identical to Mark 3 Mod 1 guns with the trunnion hoop and elevating band removed and with the threads formerly under the trunnion hoop being continued to the rear of the gun. 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
