note received from Sa'ar Nudel, a friend in Israel:
"Hi Hal First, the green horn hilt, its form and construction is strongly connected to machetes/sabers used in Cuba, Mexico and around from 1840's untill WWII. Some of the better-quality items were made (of course ) in the USA for export (Collins- see the book about, by D.E.Henry).Second, ring-guard knives were briefly popular along the southern US border during the late 19th century. And third, the leatherwork of the sheath is clearly Central-American, with the typical triangle "frog hanger" on front. This knife may have been a cut-down machete, re-finished to a Zapatist taste."
