I found a pin with crossed short swords and upon close examination found that one of the swords has a uniformed rank UR on it with a lily symbol between the letters, it also has a c under the cross point and has a O above and is missing a letter or two to the left of it. it is very similar to a cavalry crossed sword design. I know it must be between the forming of the UR and the spanish american war but not positive. has anyone seen a similar item ?
