Dad brought a grinder to take down the big 10" bell (the bolt holding it to the facade was rusted), but I didn’t think to get the backboxes with it… Would’ve tried, if I knew. I only had two days to work in the building before the asbestos abatement team returned to work, and I was focused on salvaging as many of the indoor devices as I could.
Just looked it up. Those signs are rather unique.
That’s really sad… It’s the same in my area, with almost every town replacing their old schools (some of which I’ve gotten tours of) with new ones. All gone too soon… At least some of them are still around.
