A richly embossed oxidized bronze escutcheon of exclusive design and graceful proportions. Figures and graduations are illuminated from the back.
AMMARLUND now offers a new illuminated drum dial of unusual beauty, rugged design, and distinctive mechanical features.
It is controlled by a knob, cleverly planned to be placed in any position on the panel, desirable for attractive balance.
The driving mechanism utilizes an exceptionally strong silk and linen cord, gripping a drum, snubber fashion. It cannot slip — absolutely no backlash or lost motion.
Thoroughly tested for wear under actual working conditions, this cord withstood 36,600 full-range movements of a large multiple condenser without stretching, fraying or breaking. It will never receive similar treatment in average use.
The original Hammarlund two-finger-control Drum Dial, introduced last season, will be be supplied for those preferring that type.
If your Dealer can't supply you, write direct to us. Ask for Hammarlund literature.
Back View
Note position of the Control Knob. By using a Condenser Shaft of suitable length, the Control Knob may be placed at any desired distance from the dial, thus giving a pleasing balance to the front of the panel.
