If this is inappropriate place or post, please delete. I just hate to join a light bulb forum
for a post or two.
I met a gent back in the late 70s from England who was lighting his house with the type
of bulb pictured below. In fact he was lighting his whole house with this type of bulb. Kinda
cool as it glows yellow, not white due to AC voltage required. Anyway, it is
from England, approximately 1912. Anyone know the bulb's worth?
The filament is straight wire (not coiled) and has two giant loops, terminating near the base.

Cheers and thanks.
