Pattern of 1914 Star (P.-'14*) made by the Remington Eddystone Arsenal in Pennsylvania for the British Army in 1916. This rifle is about halfway through the contract.
In 1926 these rifles were renamed to Rifle Number 3 Mark 1*(E).
Yes, an American Model of 1917 stock can be used; it was an approved Canadian mod during the Second World War.
This rifle has had the Volley Sights removed, which was pretty much standard, sold surplus following WW2.
They have Enfield-rifled barrels, 5 grooves, very deep, same width as the lands: can be very accurate, prefer flatbasd bullets and last halfway to forever.
This was designed as the Pattern of 1913 to be the ultimate perfection of the bolt rifle and it very nearly made it. P-14 in .303 was a wartime expedient, as was the American Model of 1917. MANY parts interchange between the rifles.
The P.-'13/P.-'14/M-1917 was developed in peacetime into the Remington Model 30S, then into the 30 Express, then into the 725 and 720, then into the 721, 722 and finally the 700. In Connecticut, it became the Winchester 54, then the 70..... and thus the direct ancestor of nearly all modern bolt rifles.
It is strongly based on the 95 Mauser, very much beefed-up.
Reliability is extreme.
Grandpa has good taste in rifles.
