Here is a museum quality reproduction of the very scarce leather saber knot issued for the M1913 Patton Saber.  This knot, like the saber, was standard issue until the saber was discontinued in the mid-1930's.  This reproduction is marked with ficititious inspector's initials "WPG" on the inside to inhibit sales as a fake.  As always, I guarantee satisfaction.  Check my other ebay listings for a lot of quality reproductions of hard to find militaria.
