Celadon teapots? Old or new?

[specialtysavings]

I would like some informationon a Celadon teapot I have but cannot find anything at this time.  It has a type of fish handle and a boar?s head for a spout complete with teeth.  There is a 5 shaped clover hole in the base.  It has Chinese markings on the bottom.

Its quite difficult to say if it's old or new as they still make them (with crazing from new) what does the base look like ? are the chinese characters in a lozenge or cartouche ? is it similar to the one on this page ? http://neeracha.blogspot.com.au/2010/07/of-terracotta-and-teapots.html    pictures are best.
