Thanks. I'm pretty sure that the original dial lamp was painted black on the tip and frosted. I've seen photos and several references to this bulb. I suppose this was done to diffuse the light evenly across the dial rather than have a glaring spot in the middle. I remember reading some reference to the bulbs having horizontal filaments, which I guess would be for the same reason they were used in the shadow meters.

I can etch the bulb for frosting and use high-heat paint for the tip, but I don't know if anyone sells bulbs with horizontal filaments.
