The maximum elevation was 65 degrees and total traverse was 60 degrees for the mm gun, while the Filloux type variable recoil mechanism permitted a maximum recoil of 60 inches and a minimum recoil of 24 inches. The carriage's hard rubber tired wheels, while adequate for the slow moving tractors then used to move field artillery, made it obsolete for any fast-moving mechanized army.
The carriage proved unstable when the gun was fired at maximum power, and, as an additional handicap, the ME model had been specifically designed to be divided into two separate loads for transportation, particularly when crossing bridges. The Ordnance Department tinkered with several other experimental carriages during the s, but without success.
Then, in the summer of , Rock Island Arsenal developed the radical split-trail T2 carriage which contained at least two "firsts" for heavy field artillery carriages: an all-welded construction and a unique 8-wheel four dual tires roll-bearing bogie that permitted the gun to be carried on truck wheels cross-country at high speeds. For stability in the firing position, special built-in jacks which eliminated the need for a crane dropped the bottom carriage to the ground.
This T2 carriage survived for over 30 years without any major modification. Meanwhile, both a new mm gun and 8-inch howitzer had been designed to share this radical T2 carriage, being type-classified standard as the M1 in July The M1 mm gun soon gave way to the improved M1A1 in June which, in turn, was superseded in March by the M2 model designation changes reflected the different type construction of the tube and breech ring.

By the dawn of , only 65 M1 Long Toms had been built. With another conflict on the horizon, production quickly increased. Often, the guns worked in platoons containing six of the heavy cannons. Long Toms were known to be able to strike at great range, yet were still powerful and amazingly accurate. M1 mm Long Tom history During the interwar period, the American army sought to build a powerful artillery, drawing on the lessons of the First World War. Suivez D-Day Overlord :.
