Not an area I am familiar with but I took a punt on this. Rather a gamble as these are the only pictures. Could be a tourist thing? I believe the diameter is 51cm. It might be possible, looking at the detail on the outer edge to accept the sellers notion that is is "OLD" The double bird imagery reminds me of Africa. I do not know what the animals suggest? If it is a tourist thing, crocs? eating what looks like your pet dog seems a really strange way of selling it! Follow up when I have it.
