On my two BSA P-17s, I didn't find a factory name. Between the wars they were refurbished, something to keep the armorers busy I guess , since they had interchangeable parts , the parts were interchanged. So even if you find a part with a W, it doesn't mean it's a Winchester, it just means that part is a Winchester. They made couple of million or more of the 30-06 version. It works better than the 303 .
They are very accurate . Between the wars the competitors at Bisley (sp) used the P-14. Bisley(sp) was the British Empire Army rifle competition. General Hatcher considered theP-17 the best battle rifle of the first World War. It was the dough boys main battle rifle.
By for the nicest variant is the Remington M-720, modified to compete against the Winchester M-70. But the war stopped production, they only made about 1500.
