Well I'm not saying mine has "ornate" bands, but they are white metal, unusual for a panabas still. It formally belonged to Cato and the spine of 15 "x"s is pictured in his book, p.92, photo #58.
Say, is it me or is there a theme?
So far, the ornate ones (excluding those used exclusively for war) appear to be what Cato calls the "scimitar" bladed types.
