Sealed beam headlights

[Gufshoz]

I was cruising through the posts and saw where modern points and condensers are considered “obsolete”. (Do I need to stock up or horde them?)
My father converted the headlights on my ‘30 coupe to sealed beam back in the 60’s. I had one go out and cannot find a 6 volt sealed beam headlight anywhere. I could convert to halogens, but then I’d have to replace everything except the buckets.
Does anyone know of a source for 6 volt sealed beam headlights?
