Thanks for the pictures Tim- I think you win with that scarf pin bulb if it is carbon- such a small one indeed. Suppose only a microscope could look close enough to be able to tell though.
I`m pretty sure your frosted Edison lamp was made as a christmas bulb, 14v was the standard voltage for series Carbon light sets (8 bulbs x 14v = 112v, close enough to 110) although of course the later tungsten ones sold up to the 70s were 15 or 16v due to the slightly higher line voltage found in most places by then. It`s exactly the same shape as the handful of carbon "pear" xmas bulbs I have here too. According to an anecdote I read on Bill Nelson`s web site, early Edison xmas bulbs had labels on, just like their bigger counterparts.
The odd shaped one on the right of my photo I believe is officially "s" shape glass, probably an S-4 or S-5 (it`s packed away safe for now so I can`t measure it). I havn`t seen them elsewhere either, and no idea what it was used for, or why it`s that shape.
Actually these 3 were being sold as one lot- the cute little Edison Carbon label on that one was the thing that made up my mind that I simply must get them (though I`m pretty sure I`d have got`em anyways)! Relative to the bulb size, it does seem a little big ?
Here`s a pic of the other two glowing, in case you were interested to see them....
