posting here as no real idea of origin - but guess can be moved if people wish.
In Barry Skelcher's 'Big Book of Vaseline Glass' (page 183) there is a vase/celery of this identical design, although with a flared rim shape rather than this slightly in-curved look. Not sure if the colour in the book is true to life - certainly this one is a very oily yello-green which believe common during the latter part of the C19.
Skelcher was unaware of the origin of his, but made the suggestion of possibly being from Ed. Moore (with a tentative date of about 1880) - unfortunately he doesn't give the size of his, and shows nothing in the book, from Derbyshire, looking remotely like this piece. This example is about 7.75" - 200mm tall.
However, in his other book on uranium glass, Skelcher again discusses the output from the Derbyshire brothers and shows pieces which either are, or possibly are Derbyshire, which from the pix appear to have the same foot design and castellated/hooped rim as this piece.
Needless to say no marks on this one - plenty of foot wear, and as Bernard says - enough glow to set the curtains on fire. Four mould seams by the way.
Do any of the pressed glass people know if this shape/design has been attributed to either Moore or one of the Derbyshire brothers?? thanks for looking, and all replies received gratefully
