I'm restoring an old GE luminaire as a favor for a local historical society.

Since the lamp will be displayed indoors I was hoping to find a 75 watt National Mazda or equivalent bulb. Even though the Jones socket is reduced to a medium Edison base, a National Mazda type bulb looks pretty cool on display.

Anyone have an extra working 75 watt Mazda type bulb for a reasonable price for a "charity" display? It would be cool to have a working 1920s vintage lamp on display in another public museum.
Thanks.
UPDATE: Bulb acquired. Thanks, everyone.
