GE E63 Personnel Detector (Manpack)

60s-Vintage Experimental "People Sniffer" designed for use in Vietnam. Built for Aberdeen Proving Grounds, on government contract by General Electric's Ordnance Department. Really a neat piece of gear, looks like a miniature infrared-absorbtion spectrophotometer for detecting human scent. Basically complete, save for headphone and battery pack. Toothed-ball drive belt for vacuum pump needs replacement. Mounts to LC2 pack frame.
