I have an article in a 1990 edition of Australian Shooters Journal on the PH .404. Reading it find that the author didn't want to wait around for the intermittently produced African model so he purchased a factory PH ,404 barrel and screwed it into a Mod 81 Classic action. The stock on the classic looks a lot nicer with a straight comb on the butt and without the schnabnel fore end. Happy to provide a copy if anyone is interested.
