Here's an FN Model 1910 that should never be cleaned up, but just left "as is." It is the actual gun used by Gavrilo Princip to shoot Austrian Archduke Franz Ferdinand and his wife Sophie, starting World War I. It carries serial number 19074. This gun initiated an incredible number of deaths and the reshaping of the world as we know it.
Princip’s pistol is now on display in the
Heeresgeschichtliches (Military history) Museum in Vienna, Austria. Badly corroded, it was recovered from a Jesuit monastery formerly in Sarajevo, but relocated to Vienna as WWI started.
