One-of-a-kind black Hasselblad camera trigger, measuring approximately 3.5 x 3.25, used on the lunar surface by Dave Scott for photography during his three Apollo 15 lunar EVAs. The trigger is engraved on the edge with part numbers, “SEB 33100294-302, S/N-1109.” In very good to fine condition.
Accompanied by a signed letter of authenticity from Scott, in part: “I hereby certify that the Apollo 15 Hasselblad Camera Trigger included with this letter was an integral part of the of my personal camera system during our three periods of Extra Vehicular Activity (EVA) on the lunar surface during the first extended scientific exploration of the Moon, July 26–August 7, 1971. This external trigger was attached to my Hasselblad camera used during all three EVAs...The camera and trigger were stowed in the Lunar Module during launch and lunar landing. Prior to EVA-1 both were moved to the Equipment Transfer Bag (ETB) for transfer to the Lunar Rover Vehicle (LRV) for use during surface operations. During our three EVAs we took a total of over 1,000 Hasselblad photos, accumulating 18 hours and 35 minutes outside the LM on the lunar surface.
Three 70-millimeter Hasselblad data cameras were used on the lunar surface. Two cameras were equipped with 60-millimeter focal length lenses; the third had a high-resolution 500-millimeter telephoto lens. The cameras were battery powered, semiautomatic, and, for most operations, attached to our pressure suits at chest height. A push-button on the forward center of the camera activated the exposure and automatic film advance. However, because it was difficult to reach the push-button with the bulky pressurized gloves, an external trigger was installed to activate the push-button by squeezing the trigger with a glove finger...This Hasselblad Trigger has been in my personal collection since returning to Earth.”
