I have a small, individual or decorative-sized teapot with a plate. It appears to have 2 marks, one that says Noritake Nippon, the other is the RC Nippon mark. From what I have found so far, it appears to be somewhere between 1911 and 1921, but I am confused by the 2 marks. The decoration appears to be hand painted and not a transfer. It has a lot of dimension. There are a few stray pinkish brush marks.
Does anyone have thoughts? I suppose it could be a reproduction, but I don't know how to determine that.
