Seems as good a place as any to OT, but does anyone know of a vacuum tube wiki?

I may have acquired some Otis elevator power(?) tubes, but have no idea where to go for part schematics or identification. I'd love to build them into a project, but am not sure where to start.

Going even more OT, I watched a mesmerizing and beautiful youtube video about making nixie tubes.

I love craftsman videos.
