Jeremy Leach vase stamps

A great pair of Jeremy Leach studio potter Japanese inspired vases 

I have been doing research on the markings 

And to date the marks i think are right
JL  Jeremy Leach
TR Robert Tinnyunt 
M Matilda Pottery    
The Cross i think is religious 

So todate if above is correct still looking for the E mark Meaning ?

I hope you can help 

Thanks as always

The JL mark is one Jeremy Leach used at Lowerdown pottery 2001-2013. Lowerdown pottery is an L+ mark, the cross mark might be a representation of that. Robert Tinnyunt worked at Lowerdown Pottery 1967-70. There were many other potters who worked at Lowerdown with David Leach, including other nationalities.
Do you know who the Matilda pottery is? That and the E might be other potters who worked at Lowerdown.The nature of the several marks would suggest a cooperative venture which several potters would bevinvolved in. This was usually at specific events like demonstrations at Ceramic festivals, or a special show at a gallery, or an individual Lowerdown anniversary maybe.

Jeremy Leach loves his stamps. You can always tell one of his pots just by the number and variety of stamps on the base :)

Thank you for your Help
