That’s a wonderful bit of research, thank you very much for sharing. It sounds like you had a good time. I hope your wife was still in good spirits after the “ten minute” project!
I found it a little humorous and ironic that this Diebold door was being serviced by Mosler, since they were direct competitors. Also because Mosler went out of business in 2001 and Diebold took over servicing Mosler’s products. This also suggests the door was no longer being used after 2001.
I don’t understand what’s going on behind the glass. It looks like somebody cut two thin wood panels to cover the metal, and did a so-so job of cutting out all the holes for locks and such. I’ve not seen that before. Did the Mosler service-person want to hide big bold DIEBOLD lettering? I’d really be tempted to try to dig into this but you get into arguments of restoration versus preservation and it could turn into a biger project. The only door I’ve seen with any lettering on the metal was an old HHM door where Diebold apparently added lettering because they took over HHM; all other true Diebold doors only had etching on the glass, and since that’s not the case here (except the time lock door) I think the glass has been replaced.
At the top of the door is some sort of alarm cable, I assume, that was clearly added later, and rather poorly. Possibly another retrofit by Mosler.
