I was at the Admiral Vernon antiques market in Portobello. One of the stalls downstairs sells Asian/South East Asian antiques. I bought this unique piece of foo dog/guardian lion brass. At first I thought it is a barong: a good spirit in a Balinese mythology. But looking at further research, I think it is a Chinese foo dog or guardian lion who guards/protects places.
I am not sure about the function of it, it does have small holes maybe for screw? I thought it was for topping the wine bottle, but I later doubt it because of the heavy weight it carries.
I have to come back to the seller and ask more information about it. Including where it was made. Maybe it was made by Indonesian artist? I will update this page as soon as I find more info.
