Hi, I am looking for pattern/company that produced this teapot and the approximate year. I looked on ebay and scoured the internet, but didn't see any just like it. One lady suggested it might be gaudy welsh?? Any help would be appreciated. It was my mothers and I have the original ad from the auction where she bought it, but it doesn't give any clue. The only mark on the bottom is the number 658 in same green paint used on the teapot.
