The Victor O was introduced in 1908 as a basic model phonograph. Selling for $17.50, it featured a single-spring motor, a small painted horn, and a tapered tonearm. The cabinet was a simple oak box (mahogany was used on late production models). The Victor O used it's own low-cost special soundbox, shared with no other model. The O was produced up until 1920, by which time it's price had been raised to $20.00. Approximately 50.500 of these phonographs were produced. At present, there is not a good correlation between serial number and production date for this model.
