Hoping you're cozy and warm today! This model was made around 1920 by the Lennox Furnace Company of Marshalltown, Iowa. The aluminum model was used by the Warm Air Heating Research Laboratory of the University of Illinois, probably for marketing purposes.
The model represents the Lennox's Torrid Zone domestic furnace number 50-27, which is stamped on the fire door. This furnace type is shown in a 1929 Lennox catalog and offered for sale at $112.00. It was intended for domestic heating installations.
