Good Morning ... the first thing that I asked myself was 'what are they for?' That isn't obvious from the pics. So then I asked myself, 'why six'? And the first thing that came to mind was a Table Setting. So, then looking at their size, and their weightiness, I am going to opt for a set of knife rests.
I don't think that they'll be solid silver, something of that nature would surely have some hallmark, so probably silver plate.
Just need to try to find some Art Deco knife rests similar to yours!!!
Anyone else any ideas?
