CV or GV mark - Geoff Wilcock

Could someone help please with this large jug that I can't remember how I came by. It's been hanging around, I've had a pop at finding similar but I'm not sure about it.
I think the letters CV are on the base.

I recently bought this quirky little citrus juicer and would love to know anything more about it, especially the maker or pottery from which it came. I found it in a charity shop in Somerset, South West England.

Max length is 20.5 cm / 8.25 ins.
Max width is 11 cm / 4.25 ins.
Hieght is 7.5 cm  / 3 ins

Engraved on the base are the initials GV.  I have seen the same monogram on other pieces but no one seems to specify a maker or studio.

I think the yellow is a glaze and the green and ornage/red are over-painted.

Thanks in advance for any information.

Almost looks like a No 3.
The style and colours looks like it's from the 1920s/30s.
Czech or Japanese spring to mind.

Thanks for that. I had thought maybe that era, in style at least.

Yes, No. 3 was my first thought but from other pics I've now seen I believe it is GV initials.

Thanks Naomi, that looks like a definite match for the intitials. Much later than I thought.
