Sculpted ceramic vegetable

Ceramic sculpted vegetables, purchased at the local boot fair a summer or two back. Never displayed or researched them before now.
Any help with ID appreciated.
They have a touch of the Raku's about them. A slight irredescence that is exaggerated by the camera flash. No signature mark that I can see on any of them.

When talking of ceramic fruit and vegetables the first name that comes to mind is Penkridge Ceramics. But Penkridge pieces are normally quite life like. Might be a place to start tho.

Thanks for the links Phil.
Yes, I discovered a few Penkridge pieces online. As you say in your message, very life-like and quite impressive. Also signed, unlike mine.
Thanks again Phil, much appreciated
