I have a pair of residence made copper inside or outside lanterns. These were made probably in the '60's and never ever used as for I understand. They have been in a box for life.
The only work that they need is the glass needs to be safeguarded in some way with caulking and I assume the wiring should be redone as that is quite aged also. The images reveal paper inside. That is to keeping the glass in place. The different, hexagonal piece in the images is the base that fits onto each torch.
These torches would certainly look remarkable on the ideal building. You will certainly not view these anywhere else.
