Mine does not have the crossed swords and crown on the guard like I’ve seen on some of the others. The ricasso shows Artilleria National on one side and the numbers 12514 on the other. Black painted scabbard. It’s in good condition with a nicked up blade and evidently sharpened more than once. No way to be sure if that was due to kids abusing it in the backyard or not. Any ideas on the time of manufacture?
