Hello mdchachi,
Thank you for your response. We also thought that it could have been made by a local craftsman. Yes I have been trying to look for something similar on the web, to no avail. I have the impression that the burn marks (see above) have actually been burnt over two circular marks that were there before, though this is just a guess and I could be wrong. A shame if they are burnt over some clues to its origins.
The yahoo auctions is a great idea, thanks.
