The object comprises a group of similar pluggable relays and parts. There are ten complete relays. Each is a pluggable module with 16 male pins on the insertion end. At the outer end each has a small white paper label with a three-line number, for example "SD A11 209" and "PC A11 206," which probably identify them as to location or function in the machine. Besides the complete relays there are five empty blue covers from similar relays. All were packed tight in a gray plastic box which was probably not originally related to them, just a convenient container.
