Historic and technical information
Denomination :     BL 10-pdr mountain gun Origin :       ( Royal Arsenal)             ( Elswick's Ordnance Company (Armstrong) )          

Historic context :

In 1901, the British army decided to replace its old muzzle-loading 2.5 inches muntain screw guns by a more modern version on a brrech loading principle. Even if that improvement allowed a big increase of the fire rate, the new gun still did not have any kind of recoil recuperation system.

The 'BL 10-Pdr mountain gun' was, like its predecessor, a 'screw gun', meaning its barrel could be dismantled in two separate sections linked by a screw profile. It was also a little bit more powerful with an increased calibre of 2.75 inches (96.85 mm) compared to the old 2.5 inches (63.5 cm) calibre.

This gun became obsolete like many others at the same time by the apparition of the recoil recuperation systems, and was replaced from 1914 by the BL 2.75 inches mountain gun designed in 1911, but many such weapons were used by the colonial or territorial troops in their fights in the Middle East, at Gallipoli, in East Africa and in Palestine.
