Interesting photograph of Spanish and U.S. troops fraternizing following the fall of Santiago, Cuba.  This probably explains the large number of Spanish buttons, badges and buckles that seem to show up on Ebay.
  Under the terms of surrender, Spanish troops in Cuba, Puerto Rico, and The Philippines, were granted the 'Honors of War' and retained their Colors and Arms.  Most of the Spanish Model 1893 Mausers went back to Spain.  Like my Mauser, the rifles continued in service, underwent arsenal overhauls, and probably saw use in the Spanish Civil War (with obliteration of Royal markings with the fall of the Monarchy).
