Seiji, what about the lightbulb?
Is that original or a recent recreation of early style bulbs.
Reason I ask is that I have an Edison Gem that dates to some time prior to 1911, perhaps as far back as 1902.
It's been in the family since I was very young. My dad came home with it one day, having found it in an old basement. It lives in a whatnot shelf in an old fixture I found specifically for it.
Still works!
It's hard to photograph well well with my poor camera.
In other pocket watch news. We live in a town situated on the old interurban line that connected communities in North Texas. A depot and generating station was located downtown. The building still exists and is now a restaurant.

Just last week I decided to keep an eye out for Texas Electric Railway Company artifacts. Especially nice would be to locate a pocket watch with dial marked "Texas Electric Railway." I don't know if such a watch was ever produced by companies who sold electric railroad and trolley watches.
I perused Ebay and came up with vintage postcards mostly, but did find a Texas Electric Railway pass from the late 1930s.
Here it is with a couple of non-electric railway specific watches that could have qualified for service on such lines, an Illinois Capitol with 21-jewel 606 movement and an Illinois Santa Fe Special with a similar 21-jewel movement. Both indicate three adjustments.
More than you would ever wished to know on the local interurban that once ran through this region.

There's even a museum dedicated to this topic near Dallas. I intend to visit this museum soon.
