Comments: The molded head probably does not belong to this axe.
Technical Observations: The blade and shaft of 1992.256.137.A have a similar green and black surface, but the head is much more heavily corroded with grayish-green corrosion products. The pastiche of 1992.256.137.A included three parts (blade, shaft, and head), which were roughly cut, filed, and crudely soldered together with lead solder. The axe blade was cast and then hammered, with surface design punched or engraved in the blade. The shaft was probably rough cast and then hammered into shape; the thickness of the metal decreases as the diameter of the shaft increases. The poorly preserved head was probably made by the lost-wax process.
1992.256.137.B was previously joined to this object as well.
