Re: Bronze/Brass Oil Lamp Asia
There are a lot of modern copies of these lamps- especially ones with feline headed lids. I don't entirely like the lettering which as you say is blocky. I would normally expect an early example to have more fluid calligraphy. I don't really feel confident about the decorative band at the base either. But, overall, I think it stands a reasonable chance of being 12th-13th century. Its good news that you can't remove the patination. It suggests that it has been there for a long time. Now stop polishing it!! Or if it is an original you will SERIOUSLY depreciate its value by taking away the genuine age and colour. Even if it isn't a fake, it wil end up looking like one!
