Wurlitzer Estrella remote control

Hi I have a Wurlitzer Estrella 200 and wanted to fit a remote control. The manual mentions that the H82 amplifier fitted to this jukebox has a remote control motor (40083004) fitted and that this is to allow the use of a wireless remote control (40083 infra red). Does anyone have a remote system for sale or know how this wireless system worked so that I could make one.

Thanks,

Philip
