03-12-14: KnghifiIf I ever heard any of the classic Western Electric theater gear in my younger days, I was too uninformed to realize it. And I suspect that in many or most cases the theaters had "upgraded" their equipment by that time. Although I believe that here and there a number of smaller movie houses continued to use that equipment until fairly recent decades.
Almarg, do you remember hearing or seeing them in the theaters growing up?
Best of luck with your prospective purchase, if you decide to pursue it.
