-It's a real pre-1945 P08.
-It probably was refinished somewhere along the line, most likely by Interarms in the 1970s.
-Don't confuse it with the post-war Mauser Parabellums that Mauser did between 1969-2000.
-The price Ed quoted is realistic in today's market.
-The interarms material / box actually adds a collector interest
