thank you for your post, I actually have an Indian tea set - I had never thought to compare them before, but the style does look very similar!
It is disappointing that the makers do not sign some of their pieces - here is a photo of another owl caddy also tested for at least 900 silver. Although he is nowhere near as refined as the other - he is charming! The piece is totally unmarked.
It is great to have the feedback, I am very grateful for your input. If anybody can provide any further information, that would be great!
Best wishes, Jo.
