1910 makes much more sense. That would tally with the 1903 pattern bandolier and the transitional tunic (with longer skirt, but still retaining stand-up collar).
As IL points out the boots are much later. They are of the type I spent many hours spit-and-polishing when I was in the school cadet force in the 1970s. ABW regulation service boots did not have toe-caps. See below for the example brought home by 2420 Lance-Corporal Henry Pullin, 2nd Bn. Gloucestershire Regiment.
Pullen kept the boot because he was wearing it when he was shot in the foot at Klip Kraal (Paaredeberg). It retains the bullet hole, entering through the heel and exiting via the uppers.
I have written a piece about Pullen's boot, which can be found here:
