First, does the action have the thumb cut in the LH receiver wall? If yes, it is an early Safari, based on a military Mauser action. PH used a great many of these after the war. They then went to a commercial Mauser action, no thumb cut, various makers. Early ones (50's) look just like commercial FN 98's (although made in various factories in Europe), later one's are Spanish copies (somewhere on the action it will be stamped "SPAIN", you will probably have to remove it from the stock and maybe disassemble it to find the stamp. I have never seen any cast PH actions, although I have seen some of the Spainish ones that were so poorly polished they looked cast. Doesn't mean they never used any (although it's a statement I haven't seen anywhere else either), just that I haven't seen one. If it's one of the early ones, they are nice guns, and the later ones are servicable. FWIW - dan
