3 H.P. Collis Motor mounted on a cast aluminum base that bears the Tangley Company name. The nameplate information and the providence of the unit is unknown. The chances are what was mounted next to the engine was a Roots blower, and this handy little unit may have provided the motive power for a Tangley Calliaphone used in conjunction with some kind automobile or wagon so as to attract attention and crowds.
