Hi All, I am new here; have just posted in the New Member Welcome area. (Greetings from the Netherlands) The Hi Power I have recently agreed to purchase is in very nice condition.... This gun has a four digit SN, but finding information about the year of manufacture is difficult. Must be before 1945, since the shoulder stock was discontinued during WWII? (Not sure if the shoulder stock is matched to the gun.) I would welcome any and all feedback from you experts out there.... Many thanks!
