That looks to be "C" model. Don't lose the magazine; a replacement will be expensive and perhaps hard to find.
Disassembling the detachable magazine model is a pain. Regular screws front and back, and then there is the hidden one that came with the magazine system.
Punch out the magazine catch pin, and remove the magazine catch and spring. You will see a small allen head screw. Remove it. Don't lose the little spacer that keeps the front of the trigger guard in position.
PH assembled '98 type rifles using four different receivers:
-converted military action. Has charger loading thumb notch.
-copy of FN commercial with internal collar with only the extractor cut.
-copy of FN commercial with a cut through the internal collar on both sides, to ease manufacture.
-bastard version with no internal collar, and bolt stop from Midland 2100 design.
Second type is preferred, fourth is undesirable.
The detachable magazine conversion is a mousetrap, but does work.
When I had my shop, I had a collection of ruined barrels, of various makes, which had been fired with obstructions. Most bulged or split. PH barrels tended to break, with pieces flying away. Most dramatic example was a .30-06 barrel shattered into 7 pieces after being fired with snow in the muzzle. It was my impression that the barrels on PH rifles were hard, less ductile than other makes.
I rebarrelled quite a few PH Mausers. Barrel threads showed more variability than other makes.
Often traces of the "Made in Spain" marking can be seen on the left side of the tang. Or there will be a grind mark where it was.
PH rifles tend to shoot very well.
