Interesting "triangular" filament arrangement in an Osram low voltage filament lamp

Interesting "triangular" filament arrangement in an Osram low voltage filament lamp

One of the lamps found in the very old lot. This lamp's etch is very faint unfortunately, but strangely it is rated for 65v and has a curious filament arrangement with only 1 support. Apologies for the blurry picture as it was quite hard to capture.

I also have some 65V lamps. What would they be used for?
