The medal's obverse bears the image of early Anglo-Saxon coin with bust of King Offa above a metal worker about to strike a medal; all surrounded by border of rope and waves. In coin, OFFA REX; at bottom right, TORNEI
The reverse bears Lion rampant with tower and star over sea shells. Around, (rosetta) CINCINNATI (symbol) MILLING (clover leaf) MACHINES (symbol) LIMITED (rosetta); in exergue, 1934 - 1964; signed at bottom, B.M & F. Co LTD.
King Offa ruled the Anglo-Saxon kingdom of Mercia from 757 to 796. He is regarded as having been the most powerful Anglo-Saxon ruler until Alfred the Great's reign which started fifty years after Offa's death. Offa's reign is known for coinage that is of much higher quality than that of its neighbors, undoubtedly a reason for the Cincinnati Milling Machines Company to reference him on their medal.
The Cincinnati Milling Machines Company was formed in 1889 for the purpose of building and promoting innovative new machine tool designs, especially milling machines. The two principals were Frederick A. Geier and Fred Holz. It is unclear what significance the year 1934 had for the company and why the company, whose founders have very German-sounding names, picked a reference to the King of Mercia for this commemorative medal.
The circular medal measures 58mm in diameter and was struck in bronze. No mintage is reported.
