The unidentified coat-of-arms on the two shields includes a lion rampant, facing sinister, within a plain border. The engraving of the sword in Drummond's Ancient Scottish Weapons shows the arms incorrectly (with the lion facing the other way and a border resembling those found on the royal Stuart arms of Scotland, and also as if coloured red). Drummond also shows a red lining to the hilt which no longer exists.
The form of the hilt, and the unscrewable pommel-button with a transverse piercing, presumably for a tommy-bar are paralleled on the well-known early 17th Century silver-decorated sword of Sir William Twysden in the Metropolitan Museum, New York
