Sindy Spare Body Marked Hong Kong (Smaller Head Knob?)

Hi,This is a spare Sindy body. It has the marking Hong Kong just below the waist. It is quite a loose waist and the plastic of the body is different to the vinyl of the arms and legs. The right food has chew marks on it but it has not lost it's shape and it needs a bit of a clean.I have tried a number of my Sindy's heads on it as it is in better condition than some of my dolls, but the heads are too big which leads me to believe it may be the body of the slightly smaller "Hong Kong Dolls".The knees still It may be useful to somebody so I am listing it in case.If you have any other questions please ask, and thank you for looking.
