Really like the diversity of opinions here. Mart, the handle "grip" is absolutely wood, for whatever that is worth. My cell phone photos do not always do an item justice. And I think Cogar was referring to the norm before kerosene lamps became common.
Sugarcube, you address my most perplexing, frustrating question: "WHERE THE HECK ARE ALL THE INTERNET PHOTOS???" I am pretty certain that my candleholder is NOT a valuable treasure, but after all the hours of internet searches and photos I have been looking at, I am beginning think that there are more first-run copies of the Declaration of Independence floating around than there are of copies of this candleholder. Only slightly joking about the Declaration reference. Not joking at all about the internet search.
I have found only two other photos of an identical item posted on the internet. One person/seller is on ebay and the other is on Rubylane. I have contacted the ebay seller and here is what they said "I'm sorry, I don't know any more about this item than the information we discovered and included in our listing. Our items come from estate sales, auctions, consignments, and thrift stores. Most of the time we have little or no history on an item. I wish I could help" The Rubylane seller seemed confident that it might have been used in a wedding ceremony, but they were unsure of age as well.
And that brings me back to that frustrating question I posted in ALL CAPS above. You'd think that for such a commonly-used item (whether a tavern light or an Wedding, Mass, church service implement) that there would be more photos.
Any other tips will be gladly received.
