The Victor III started out as the "Victor M" (Monarch) model in 1901, and then was
transitioned to Victor III nomenclature around 1905 when the tapered arm was first
used, but there was some overlap in production with the M Model series. Selling
for $40.00, it featured an upgraded double-spring motor, a brass horn, and a tapered
tonearm (after 1905). The cabinet was made of oak, somewhat larger than the Victor
II, and with additional corner ornamentation. The Victor III was produced up until
the early 1920's, by which time it's price had been raised to $45.00. Approximately
104,000 of these phonographs were produced. At present, there is not a good correlation
between serial number and production date for this model.
