The bolt and firing pin look fine. Many are just like that. After 1952 or 1954??? They started cutting the bolt face back for final headspace instead of using a couple more reamers in the barrel. The firing pin may have been fit by the factory or a gunsmith, the point looks good and that is an important thing; if it cocks and goes on Safe alright it is good to go. You could check firing pin protrusion by assembling the bolt assembly and "Firing" the striker. A dime makes a good protrusion gauge for the tip protruding the bolt face. There have been some dandy extractors on the old eBay lately! You need an "A" marked extractor.
