thanks. I'll try to get a closer image of the stem. Interesting that the stem might be part of the clue. I know JWH (great grandfather, not grandfather) had a lot to do with bulb manufacture, and I think he even developed a stem making machine, if I remember correctly from reading his books.
John Howell's last surviving child, my grandmother, died only four years ago at the age of 97!! So there are not many stories I can dig up first hand about him anymore. But his book "Stories for My Children" has a small wealth of stories about his life.

Welcome to the group John. The bulb looks early to me but I would be interested in seeing a close-up of the glass stem, where the filament is mounted. The construction of the stem may provide a clue.
We would of course be interested in any stories that you could share about your grandfather?s work with Edison. I?m a big fan of the History of the Incandescent Lamp co-authored with H. Schroeder.
