3 Band Enfield, still in the field at 78+
This hardy footsoldier is described as “Sikh Sentry Srinagar” standing post in the Kashmir region in 1945, complete with a regulation Dastar (turban), and KD uniform shorts with field shirt and wool knee socks. His weapon appears to be a P1853 “3 Band” Enfield rifle, possibly converted in the 1870s to a .577 Snider–Enfield breechloader although I don’t think so as it doesn’t have updated sights.
As the last P53 was produced in 1867, Srinagar is likely much younger than his weapon, but he likely would have used it without compunction if needed.
One hardy Sikh with a bayonet and smoke pole of any vintage is a daunting sentry.
