All original hardware except for the output jack which was replaced a few years ago.
Combination of double pickups plus Atomic Logo makes this a rarity. (Most of the H46 were not produced with the Atomic Logo).
From the 1962 Harmony Catalog:
Stratotone “Mars” cutaway model double pickup provide outstanding value in its price class. Hollow “tone chamber” construction. Ebonized maple fingerboard. Straight-line hardwood neck with built-in steel reinforcing rod. Finely finish in warm sunburst effect showing the grain of the wood. White celluloid bindings. Adjustable bridge. Hinged tailpiece.
Twin built-in pickups, each with tone and volume control. 3 position selector switch permits playing forward pickup for rythm – bridge pickup for take-off or solo – or both pickups at once, for maximum tone variation.
