This may be an often asked question, but since I'm new to the forum, here goes.  How many 1896 carbines that were issued to the 1st US Volunteer Cavalry (Rough Riders) have actually turned up after all these years?  I was curious because I have one according to the serial number of my carbine, which is listed in The Springfield Research Service book.  I'm not sure of what volume, It is at home and I'm at my office.
