Would be nice to have a look inside? Looks pretty DIY, but it probably had some very specific use-case (like Madskp described) in mind and probably did that very well.
Disregarding the original function, the IR-receiver with its black stand might be the most valuable parts as that is somewhat rare thing (it’s not the MCL IR-transceiver as it doesn’t have the buttons, but the external IR-receiver for the VX5000(/BMx500 I think?))
