Not certain that this was manufactured by IBM. Appears to be scale model with only moderate detail. Construction appears to be plastic cast around wood with added details. Model depicts black cabinet with red front and container on top with circular component inside. Part of the edge around the beige bottom of container is broken into two parts kept in a separate bag. The top layer of paint on the upper left top corner has broken off. Blue and white label on the bottom includes IBM logo and printed text "Lester Associates, Inc.".
When selling large, expensive computer systems, many manufacturers created salesman models to help customers visualize what they were buying as well as to assist in planning where and how to install these complex room-sized computer systems.
