Nice DAF trucks, Pegasus. Good work, Glaciesfire!
Two Armstrong's siege, fort and naval guns, a real workhorse calibre: 4.7 inches, 40 pounder, both of them, rifled. First, the breech loaded gun, the gun involved in the british shelling of Kagoshima:
The somewhat aestetically ungainly iron parapet siege carriage was also shared with the 25 pounder (4 inch) gun. Then, after some problems with the breech mechanism, the same of the 110 pounder, Armstrong reverted to the muzzle loaded gun in the 1860s:
which introduced a metal travelling carriage of long lasting history with the Royal Artillery. Cheers.
