Gunparts is listing a mag for a PH Model 1000C, 1200C at $44.05US.
They have some bolts, that'd require fitting for headspace by a smithy(there's no such thing as a drop in bolt), but you need to know the actual model number.
A bolt made out of a 1903 Springfield bolt for the PH Midland series, runs $16.50US and needs final fitting for size and headspace.
A stripped bolt for an M98 PH, runs $73.45US for standard calibres. $89 to $96US for magnum calibres.
2 and 4 are not words.
