Lee Enfield at War

[Surpmil]

I wonder if the previous picture [A New Zealander poses with his sniper rifle in the ruins of Cassino] also features a Trials T? Is that wood relieved for cutoff and an early style cocking piece?

No sign of the butt marking disk, nor of the cutoff, though slot may be there. Possibly an early Savage MkI as they had the thick top band or at least some did, as shown in TBS p.247. Foresight protector could be the fabricated type shown in the same photo in TBS.

Could also be an early BSA as the MkI forend & cocking piece were seen on a fair number of early non-trials rifles, both trials parts left over and sent to BSA and also some early production by outside contractors IIRC. For example am pretty sure SM made the waisted foresight protectors for a short time as well as the MkI cocking pieces.

Only way to tell for sure would be a closeup of the backsight relief cut: on the (Model B) trials rifles the cut was shallower due to the lack of the backsight plunger, on the Model C trials and all subsequent No.4 production, the relief cut was deeper and cuts through the right wall ahead of the sight axis pin hole.
