A great number of these were sportered after the Second World War and into the 1960s. You will find names of the companies which did the work on many of them; Cogswell and Harrison seem to have been quite popular in Canada, along with Parker-Hale.
I have a very nice one here, Custom grade, done by BSA, and it is a real work of art. The work was done about 1960 and I have it with an original steel-tube Weaver scope. Loaded up some '06 for it and went 7 for 9 rounds on the little plates (size just a bit bigger than a pack of smokes) at 290 yards, witnessed, rapid fire. I have NO complaints at all.
No matter which company rebuilt them, the fact is that they were without doubt one of the finest military bolt rifles ever constructed. The P-'14 and its American cousin the M-1917 were the inspiration for the original Winchester Model 54..... which later evolved into the early Model 70. As well, the same rifle served as the basis for the Remington 1934 military rifle and for Remington sporting rifles such as the Model 725 and the later series which culminated in the current-production 700 and its offspring.
In other words, rifles such as yours STARTED the whole series of North American bolt rifles by the TWO biggest makers...... and it is STILL just as good as the newest.
Worth hanging onto, one would think.
