I appreciate and value your comments Ward. Thank You!
I studied this shamshir for a short while, and it puzzles me. I knew the stamp reads "AA Isfahani", but I'd love to reach an intelligent conclusion as of this stamp's authenticity (not easy, I know)

Most AA stamps I've seen are either obvious fakes, or at least old and
made in certain fashion. This one is old, I think, but made in an unusual fashion. The blade is wootz with prolongated wavy pattern. The sword's shape suggests 19 Cent Arabian saif, IMHO. My current take is: "If AA insignia played such an important role of quality and prestige, the AA stamp should represent the same". Perhaps I am being too judgmental, but the lion looks particularly unusual to me.
