Vintage Westinghouse A23(?) 200w Clear Incandescent Light Bulb

Here is a nice old Westinghouse 200w incadescent bulb! I think it's an A23, but it doesn't look much wider than an A21 when compared side-by-side! Weird. This is a very nice clear bulb. It has a nice vertical CC-8 filament that has a support but is not even passing through it! I'm not sure if that's a manufacturing defect or if it became that way over time, but very weird! This lovely vintage lamp also features a very nice blue glass insulator. Very nice bulb!
