Hi Adam,
In 1948-49 the British Government decided to get rid of soem old stock of guns held at a certain depot. The guns were all from The Great War (WW1) and included P-14s and American US model 1917's in various conditions, there were soem 14,000 of them and BSA brought them and yes they built huntign rifles on them. Five grades were offered A-E with E being the highest. They offere three chamberings .303 British, .30 Springfield and .270 Winchester. Model A's just had an inspection and the handguard removed model E's had new BSA made barrels sporting sights and a new sporting stock all were drilled and tapped for a P-H 6E sporting aperture rearsight and the higher models also for P-H scope blocks.
Of the 14,00o rifles BSA recieved a lot were only fit for scrap or scavanging for parts and thsi went on from 1949-1953 when BSA Introduced the new Hunter Rifle of their own design. So yes it's a commercially sporterised P-14
