I'm confused are you looking for the extractor or the extractor pin? You can buy pin stock from gunsmithing supply houses like Brownells then just cut and fit the replacement pin. As a gunsmith I used to buy old Junkers at gunshows and pawn shops just to have for parts. Is this a one time project or a new hobby?
