Pot/Bowl with CP mark

Can anyone identify this maker please?

The technical term for these is Porringers. They were made a lot by production studio potteries like the Leach St Ives and Winchcombe potteries. They could be produced in quantities by apprentices in training.
The CP inscribed mark probably means it was produced at Colin Pearson's at this Quay pottery in Kent in the 60's/70's

Thanks Philpot  

I don't think it's the right clay or glaze for Colin Pearson. The Marks book said he used a C.P. at one point, but that's different from this cp mark. Not one I've come across before

They look too small for porringers and look the size of ramekins to me. Also definitely not anything to do with Colin Pearson.

So who then?

Looks quite rustic. Might be European

Thanks all for yur insights

The mark looks the same as Cooper Pottery.
Although those we've seen are stamped, not hand written like this one.
