This type of 2 centimeter diameter core tube assembly was used on Apollo missions 12 and 14. Each core tube had a bit on one end and an adapter screw on the other end. The astronaut attached an extension handle to the adapter, placed the core tube on the soil, and drove it in by hitting the top of the handle with a hammer. Once pulled from the soil, the bit was replaced by a cap. Two tubes could be screwed together to make a longer tube.
The NASA - Manned Spacecraft Center transferred this core tube assembly to the Museum in 1971.
