This is a piece I have not seen before, except for one that happens to be on ebay right now about 300 miles from me.... very odd. I would comment that several companies used a similar scrolled foot design including Ruckl. I have not seen this particular shape in a Kralik decor that I can think of.
I would not term this Tango either. It is simply an orange/red piece with a black decor and feet.
I would also always include quotation marks with "Tango" when not talking about Loetz, to differentiate it's use from the proper name of a specific Loetz Decor. Unfortunately the decor name has become a widely generalized term applied to a wide variety of glass styles.
I think it is an interesting piece with an interesting decor, but at this point I do not know who made it....
