Hot Pot brass cooker - antique and tall 16"

I picked this up a couple of months ago at an estate/garage sale. The female I bought it from said that it was passed down from her grandmother and it has been sitting on a table for many years...she was moving across the country and didn't have room for it. I was very excited to get it, which worked out good (I would be very bad at poker :), because she wanted the hot pot to go to someone who appreciated it. Yes I do....I haven't used it tho. Was researching how to clean brass today, so far I've tried ketchsup...and then lemon. It does have some areas of tarnishing. I happen to think its pretty amazing...it has the most beautiful designs of fish and water...

I was also researching the official name, she had said something like Shiva, seeva,....I don't remember....
