Christine Smith, Barnbarroch Pottery, Slipware, fish mark

A charming slipware mug, with a leaping hare painted on each side, both sides initialled M or N in slip.  Clearly marked with the Hastings Pottery two-fishes seal both at the bottom of the handle and on the base - but totally unlike anything else by this pottery that I've been able to find online.  I see that the pottery was run by Bernard Cotes and Dennis Lucas, but does anyone know if any other potters worked there who might have made this?

Thank you Naomi. That makes much more sense! Don't know why I didn't think of Christine and Rodger Smith - much more their style, as I should have remembered because in fact I have one or two other pieces by them.
