Cranks (Victor referred to these as "Winding Keys").
Early Victors used Flat-Shank winding keys. Most of these cranks had female threads. The thread sizes vary, depending on date of manufacture.
Later Victors used Round-Shank winding keys. These cranks used either a male or female thread, depending on date of manufacture.
Speed Controls
All Victors had some type of control on the motorboard to vary the motor speed to match the record being played. Early record manufacturers would record at speeds varying from 60 to 90 RPM. All Victor records are intended to be played at 78 RPM
The earliest Victors and most low-priced models used a Simple Speed Control Knob to adjust the turntable speed (left). Some of the more deluxe machines had a wire "extender" protruding out of the knob to make the speed adjustment easier (right)
Some of the more deluxe models, such as the "Victor V" and "Victor VI" used a Round Speed Control Bezel, with a pointer to reference the desired speed. This feature was first adopted in late 1905.
Around 1913, the "Schoolhouse" Model (V-XXV) used a Semi-Circular Speed Control Bezel design; however, this style was never used on standard tabletop Victors.
Internal-horn Victrolas started using the Small Glass Speed Control design around 1916. This feature was eventually adapted for use on a few of the very late external-horn models around 1920. The indicator arrow displays the actual turntable speed (when calibrated), which can be adjusted by the knob.
Brakes
All Victors had a simple brake system to stop the turntable from spinning
The vast majority of Victor machines used the Bullet Brake. When engaged, a leather pad contacted the turntable causing it to stop.
Some of the very late Victor machines made in the late 'teens or early 20's used the Tab Brake. This design "hid" the leather pad under the turntable platter
