This is a Love Tester mechanism. The player puts in a coin, grips the handle on the front and the lights begin to flash. At some point the lights stop and indicate how "loving" the player is. The lights flashing are entirely random.
This mechanism has been bead blasted and the electrical contacts cleaned. The motor bearings have been cleaned and new packing put in the oil passages.
Unfortunately the mechanism is missing the part that centers the wiper on a row of contacts. This results in a few of the lamps in the rating being out. I will continue to research the patents and the other mechanisms until I find the parts that are missing. This game requires a large amount of research to get right.
