Collection Item Summary:
Extension handles were designed to be compatible with a variety of lunar tools, such as the hammer, scoop, and rake. Two types of extension handles were employed during the Apollo era; a shorter version (23.75 in) was flown on Apollo 11 and 12, and a longer one (35.5 in) was used on subsequent missions.
This particular short extension handle was used for training and was transferred to the Smithsonian from NASA - Manned Spacecraft Center in 1974.
