I have a Sako Riihimaki .22 Hornet, N 6060. It was the personal firearm of Hubert Zempke of world war II fame (Zempke's Wolfpack- fighter pilots in Europe). It is engraved with his initials. This engraving was done in Germany I believe, the engraver is unknown at this time. Mr. Zempke gave the weapon to one of his friends, my father, who was also a fighter pilot and custom gun builder. I want to figure out what it is worth for insurance appraisal,if possible. I also would like to buy additional magazines for it since it shoots so beautifully.
