Yes, I checked the Wikipedia article as well as a several others !! It doesn`t mention anything about Stiffel or lighting of any kind !! That's why the experts are skeptical of these lamps where no proof is available !! You would think that with a well known designer and a prominent lighting mfr there would be some written signature or proof somewhere !! Stiffel did have some lamps that closely match his work,, but then many others did too !! Thats what makes it difficult !!
Frogpatch worked in the lighting industry for years,,maybe he will take a look !! I personally do not think your lamps,,nice as they are, look like Parzingers work !!
Come to think of it.....yeah..You would think that a designer would have its name on it.. The only place on the lamp I have not checked is inside the lamp by peeling away the bottom...I may be amateur when it comes to antiques, but even I know that is not a good idea...
If you were to check a certain online auction site...you would think every Stiffel lamp was designed by Tommi Parzinger.
Probably the most frustrating question I would like answered is that I cannot find a price guide for just Stiffel lamps or that covers Stiffel lamps....I realize that are numerous categories of vintage/antiques with a huge amount of items for each category.....But still.....oh well....
And to think...I was about one hour from posting these lamps for $10-$20 a piece on local Facebook Garage sale Group after I acquired them...I thought they were just neat table lamps (bought at a thrift store) that would work for our new house......But we discovered that we need taller table lamps, so I was just going to sell them and try to get as close as what I paid for them and move on..
But something about these lamps bothered me....so I kept looking at them and discovered the word Stiffel and the rest was history............
...I just like a good mystery...
I only paid $4.00 for both lamps....
