Extension handles were designed to be compatible with a variety of lunar tools, such as the hammer, scoop, drive tubes, 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 long extension handle was used for training and transferred from NASA to the Smithsonian in 1972.
