Qianlong teapot

This teapot was purchesed while on holiday ih Hong Kong. We have seen this teapot in an old Carters Book some 12 years ago, it was quite valuable. It would be great to learn of its history and markings, and if it is the real thing so to say, perhaps consider getting it carbon dated. One of course takes risks when purchasing items overseas, and we know there are a lot of fakes out there. But who knows it may be valuable to a collector. Please respond, many regards Chrisco.
