1937 Mlps signal

We just purchased this traffic signal. 8" square and 5 ft high. 110 motor (forward and reverse) hooked to a transmission (reduction) that allows the cyclinder to rotate 90 degrees and then back. We would like to make it work. What kind of switching would we need? We have found pictures from 1937 and 1940 from Minneapolis historical.There are bulbs on the inside to light up "stop" and "go". Ican be reached at 715-268-2505. Thanks min advance. Larry
