I, for one, am not sure who these are by. They have a resemblance to the Martelé décor by Kralik and Rindskopf. The issue I have with them being one of those two, is that the Martelé decor by the companies I am familiar with is that the decor is generally a little tighter pattern. These have some very large clear areas in the decor and that just not fall in line with Kralik & Rindskopf Martelé examples I am familiar with. In this case, the color is also a little different. I have seen a couple of examples of this décor recently, and on this shape if memory serves me correctly.
I can say pretty confidently that they are not Loetz.
They are, at least for me, a bit of a puzzle at the moment.
May I inquire if the rims are Silver and Hallmarked?
Period wise these are likely ca 1910. Pretty examples in a different color...... and I love pairs...
