Merged threads.
They're No4Mk1 Lee-Enfields, a WWII-vintage rifle that served well beyond WWII, even in Britain until the L1A1 took over.
The Indian-manufactured Ishapores are even more "modern", in the sense that they built on the NoIMkIII SMLE action, albeit chambered in 7.62mm NATO (aka, .308 Winchester) and using a stronger grade of steel.
Regardless, a Lee-Enfield in the hands of somebody who knows how to use it can be formidable, indeed. Google the "Mad Minute" I mentioned above.
