What is it worth?

Those two boxes on the left are audiocom, and are the same series they currently make. The ones on the right are the older audiocom from what I can recall. I have not seen that exact base station or those exact remotes. Looks like early 90's stuff. I know those headsets go for about 150 or so a piece new. I believe BMI is a full supplier of telex, might want to give their catalogs a look to ballpark it. Each one of those boxes usually goes for around a hundred.
