Longton (Stoke) factory

I am currently researching the little known Longton (Stoke) factory of Charles Heathcote & Co and its association with the William Turner factory patterns. I would appreciate knowing of any items from this factory with either of the two marks in the images attached, one impressed and the other printed. There are some entries in the TCC Database under this maker but there are other patterns not included. Additional information and mark. Please respond to ballaker@pettonhall.uk
