Once the regular army had upgraded to the charger loaded SMLE Mk.1 and Mk.3, how did the part-time Yeomanry (the Territorials, forerunner of the modern Territorial Army) get a cost-effective upgrade? The simple answer is that earlier patterns of Long Lee Metfords and Lee Enfields were given an upgrade to their sights, and the charger bridge off an SMLE Mk.III, basically giving full throat to the lessons learned in the Boer War without going to the much higher cost of converting the earlier rifles to SMLE Mk.2 (con'd) or Mk.4 (con'd).

This particular example is a CLLE Mk.1*, converted from a Magazine Lee Enfield Mk.1 and not upgraded for Mk.VII ammunition.

It's marked to the 7th Battalion Notts and Derbys, i.e. the Robin Hood battalion of the Sherwood Foresters.
