1) The style bulb featured in the OP's picture is not the "original" Edison style bulb.
An early style, yes.
Not trying to be pedantic but my grandfather bought a "50th Anniversary" reproduction of the original bulb.
They kept it in their curio cabinet and my cousin has it today.
I just had to speak up because I think that repro bulb is the COOLEST THING.
Imagine the limited list of note-worthy products which were reproduced: Certain bicycles, a Wearing blender and several fountain pens.
You won't see "original" washing machines or TVs issued commemoratively. That's for sure.
Hmmm....Ford's Limited Edition Commemorative Model T ? NO. We get a listless Thunderbird on a Lincoln pan.
When the State of New York-through a historical site reconstruction/preservation law- funded the resurrection of the New Amsterdam Theatre in NYC the designers (Disney) selected these very bulbs as they were clearly seen in many photographs taken in the '20's and '30's.
FYI: Another old theatre in Buffalo and 6 sites along the old Erie Canal were included in that funding law.
WHOA, that was a trip down memory lane, a fact transfer, a rant and a vent all in one!
