I have contacted Kate Pinsent(the late Jill Bennett's daughter) who has confirmed that she is probably her late mums design under J Designs. She is poseable and you can see the legs are constructed with stainless steel multiwire to allow movement. Adorable sweet expression, and lovely clothes please note she is vintage, there is slight paint loss on tiny spot on one foot and hands please see photos.
Please see the photos as they form the description. Any backgrounds/ pound coin/ ruler for illustration only not included.
