Does anyone recognize the maker or name of this teapot? I found this at an antique mall this weekend and just couldn't pass it up for the price. Problem is I can't find it anywhere on ebay. The flower is apparently a hibiscus and the antique store critters thought it would be either unmarked Mc Coy, Weller or Brush. The only markings are an inscribed 5 and a painted 8 on the bottom. Any ideas?
