Westinghouse OV-15 from '77 (missing glass), GE M-100 from '63, Westinghouse OV-14B from '57, Wheeler Boston open merc from the 60s, Holophane teardrop from the 40s or earlier.
Wheelers are really cool, I haven't really seen them in service.....But GE M-100 are there and here (mostly the eastern area of my electric company) has those GE M-100 and A LOT more Westinghouse MO-8s!
Update: I put in one of the Canadian Westy mercs in the OV14B and it looks great! Ideal combination, except the lamp is 25 years younger than the OV14B lol.
