Welcome ffp,I believe this is surely a derivative of the Pangaea winged sword of the Calaberea. One was found in a river in Ski Lanka in 1930, and as far as I know, only one was ever found. Professor Johnathan Michaels III, head of a large expedition including five American male grad students, three French females, and numerous diggers and on lookers, brought his treasured find back to the New York Museum of Archeology: one of the greatest mysteries in modern archeology happened when not only the sword disappeared, but all pictures, files, and other data. The mystery was further compounded by death of Prof. Michaels in a horrific alligator attack in the Florida Everglades, where he was on highly secretive expedition, reportedly seeking the fountain of youth.
There are others on this forum, Horseclover, Crimson Falcon, and so on who are much better versed in the legend of the Pangaerian Sword and this fascinating man of action, the original on whom the the Indiana Jones movies are based . These experts are quiet men of deep knowledge and may choose to remain silent, we can only hope they chose to share their sacred learning. It certainly is an alluring and fascinating legend, likely based on history, and I wish you fair sails as you move between the fairy waves of the"green dragons breathe".
ffp, I couldn't resist a little tongue in cheek humor. I can't help you with the classification, it doesn't seem to be any one recognizable style.
