The “scharfes S” is called “Eszett “ in German and depending upon its location with respect to vowels on either side or at the end of a word can represent “sz” or “ss”. The letter on the Russian replica Luger is the old Fraktur letter whereas the more modern letter resembles the lower case Greek letter beta. Prior to the spelling reform of 1996, place names such as Russland would have used the Eszett for the double s. Subsequent to that date it would be spelled "Russland" as we do now. Given the 1906 date of the Luger that the replica represents, I believe the Fraktur Eszett would be correct. But as usual, I could be wrong.
