Embossed with DIETZ FIT ALL NEW YORK USA. It was hard to photograph where it would show up but I tried. It looks like the corners of the frame have been soldered at some point.
There is a little wire guide on one side that the wire passes through to raise and lower the globe. The guide is missing on the opposite side. It doesn't affect the function but it is missing (see last two pictures). I don't know if the burner mechanism works, I never messed with it.
Please see pictures for condition and let me know if you have any questions.
