It appears to have been taken at Neuve Chappele April 1915. The original caption idicats thatit shows the gun crew having died at their station. The photo is not very clear but I cannot see how this gun vould be elevated or for that matter any recoil mechanism. Is it what it proports to be ( a field gun of some kind) or something else?
I'm no expert, but it appears to me that this is by 1915 a rather aged Gun from the 19th Century. I'm sure some other useres will know for certain.
Thats what I would have thought but if this was so you'd expect to be able to see some trunnions on the barrel. Iv'e never seen any 19C gun with a big flange joint mid tube as this one seems to have.
This is a frontal view of a British 2.75 inch BL Mk.1 mountain gun with a metabolically challenged crew member on the ground next to it. It was one of the uniquely British 'screw guns'. They were used briefly (hence their use at Neuve Chapelle in March 1915) on the Western Front in an Indian Army mountain brigade sent later on in 1915 to Egypt. The 183 guns made between 1914 and (ca. 1917?) were all subsequently used in India, 'Mess-o-potamia', Salonika and Egypt.
