Yixing clay teapot

Can anyone read Chinese pottery marks? I've spent hours looking at them and trying to identify this pot.
I have almost identical one here: http://en.wikipedia.org/wiki/Yixing_clay_teapot , the one on wikipedia comes from Shanghai museum and was made around 1900 but there is no mark available.

The pot is beautifully made, really nice quality. It is stamped to the base, to the back (just below the handle) and the lid is also stamped.
Even if this is a reproduction I guess it was a bargain for a pound :) The lady who sold it to me said that her mum brought it back from China in 1970's. I'm guessing this is a later example but cannot confirm as I don't understand the marks.
Any opinions on this one?

Bump   

I can't read the marks but I suspect all they would tell you is when and/or by whom the original of which this is likely to be a copy will have been made. When making wares in homage to something from the past it would be usual to copy the original marks as well.

It was a bargain but there is nothing to suggest that it was not new when the person bought it in the 1970s and I daresay that they are still being made.

I agree, it is probably modern copy. Also you can see on the pot from the museum that there are small imperfections to it, this one is completely smooth. However even a modern pots are sometimes by a very good makers, just look up for example Gu Jingzhou...
I have tried everywhere to find out who the artist was, obviously without success   

I know how difficult it is but if it is by an individual potter then it is almost certainly going to be the mark at the base of the handle that is his mark and not the mark on the bottom or the lid.

I got the info now. A specialist from Bonhams said that it bears a Chen Mingyuan mark, one of the greatest yinxing makers... However, it is probably late 19th or early 20th century copy, not 17 or early 18th. Still, worth about 1000 more than I've paid  

Great result! It's certainly not a shape I've come across before so good to know it's a pedigree piece.

Yes Naomi, only one I've seen before was here: http://en.wikipedia.org/wiki/Yixing_clay_teapot
Unfortunately mine is a later one.

What am I saying? It's not later, but has a mark of a potter that lived much earlier
