Early light bulb
Early light bulb larger than the usual size with a turned brass base filled with plaster of paris. The following markings are round the base of the glass envelope "J 109" "8" and in large letters "89" could this be the date?
The double loop filament is in good condition and normal - I guess it just looks odd in the photo because of the angle.
Postage is much cheaper per bulb if you buy more than one. I guarantee to get bulbs to my customers intact.
