... The "S" after any neutral non-ampersand symbol on EP marks is usually Sheffield. ...
I came across a lonely EP "S" today that wasn't Sheffield. It's the mark on an EP handled holder for a Pyrex mug with the early PYREX/JP mark. The mark starts "S·???", which turned out to be one of the marks of Suckling Limited, Birmingham. Here "S" stands for Suckling.
Christine — "Preserve Dish" is what I will call it. Thanks.
