Hi Pamela & Ivo, and thanks for your thoughts. After seeing your earlier replies, I made a start trying to find any similar Ikora pieces to compare it with but without much luck.
I've just come back to my PC and found your last message Pamela ~ am I right in thinking that, from the link you posted, it is definitely Ikora? I can't see anything the same there, but it certainly has some similarity to #v32. Should there be a makers mark on it if it's Ikora? Or any other 'distinguishing features'?
Sorry if these are silly questions, but I'm intrigued!
Thanks again for your help, John.
