Light Cruiser Undine
Launched in 1902, this was typical of the protected cruisers armed with these weapons

10.5 cm/40 SK L/40
The gun pictured above and below is now at Memorial Park in Cambridge, New York.  This gun was originally on either the gunboat Tiger or the gunboat Luchs.  After those ships were moved to Tsingtau, China, early in World War I, some of their guns were removed and then mounted on the Hilfskreuzer (Auxiliary Cruiser) Prinz Eitel Friedrich.  Following a successful war-cruise where she sank eleven enemy merchantmen, this ship entered Norfolk, Virginia, for repairs on 11 March 1915.  She was subsequently interned at the Philadelphia Navy Yard, Pennsylvania, and then officially taken over when the USA entered the war in 1917.
