I don't know what it is, but call Marty Richter at 1-626-914-9434,
in Southern California; he is a mobile jukebox repair person, and knows
a lot about jukeboxes.  Maybe you could talk to him and send him a
photo of the Juke and maybe he'll recognize it.  Try also Yahoo, and
maybe they have a Jukebox search word!
