Hey everyone. New to the site, hopefully posting in the right forum. I have an old Collins and co legitimus machete and was looking for some more info on it if possible. It says No 460 below the made in USA stamp. It measures approx 23 1/2 inches blade length and has a 5 inch handle. I found similar blades through Google and some had a year stamped in them and some said 460 like mine. I was wondering if there is anyway to date the blade. Any help would be appreciated, thank you
