Tankard JL mark and EP mark (not Jeremy Leach)

Jeremy Leach tankard JL and unknown mark
I see all sorts of marks on Jeremy Leach pots.
I’ve not seen this decoration design of tankard before and I don’t recognise the other mark.it’s like a curly E& mark. Possibly a slightly older piece than some I see.
?

I’ve come across this pair of marks several times but still a mystery. Unlikely to be Jeremy Leach, tbh. It’s closer to John Lomas’ mark but his was in a square, and no mention of him working in a pottery other than his own. 
The EP mark could be the Pottery‘s mark. It’s also been paired with an AR mark
 

Thanks Naomi. I thought it would be Jeremy Leach as there are so many pieces with JL and other marks. But it’s different in style and body to what I’ve seen before. So you’re probably right it’s someone else. A mystery for a bit longer.
