Nice pics of both swords. Gene, I like this Dutch hanger very much, especially the lion motifs carved into the ivory hilt. Back to Fernando's sword. Having seen the blade, which is also a classic hanger pattern, I stick by my original opinion of American, possibly made in New Spain for the market. Hartzler's book really is a valuable source, with multiple pics of eagle-hilts from the original Medicus collection plus many 'one-offs' like this one. Most colonial Spanish swords didn't have hanger-type blades, but more of the straight espada types. The few I've seen with curved blades were either massively long, or of a more crude construction. Not so sure about those marks-
It should be noted that the two most common types of weapons with eagle-type hilts in this time period were American and/or New Spain/Mexican.
