Could somebody give me an answer to the impressed mark on this piece of pot

Very large vase with turquoise finish to the inner and glazed only on the inside

Could we see the rest of the pot, please.

Of course here it is

The mark looks like a CL or G (or maybe LG). The decoration reminds me of Bristow Studio Pottery, Chillington Devon, but it's not their mark. I've wondering if it's even British. It might help to have a photo of the whole base, as it looks like there may be a deep foot rim, which could indicate a foreign manufacture.
Jury's still out on this one.

Here is the base, thankyou
