Rollei IR 02 Infrared Remote Control for slide projectors (Used)

Cat. No. 591040-Used-2021 Rollei IR 02 Infrared Remote Control for slide projectors (Used) This looks like it's been it's original box for a long while - maybe never used, but I don't know. The box is worn and it doesn't have a manual.   I don't have a projector and haven't tested it.   I'm just hoping someone needs this.  Not tested, no returns, priced with that in mind.
