Flying free, NevB.. Thanks for the response and input :)
Flying free - There are no markings underneath, at all (unfortunately) so the hunt goes on. Thanks for the cheery response, I like it too, I just want to try and find out more!
NevB - Oddly enough, the piece you referred me to came in the same auction lot!, (Image of the lot attached, just the three black pieces, not the two green pieces, that's a different story!)
The Sowerby 1388 Tea Caddy in the image on the glass gallery could almost be the same piece as the one I bought - exact same date and batch number stamp!! :)
I have had a good look around and the only pattern I can find for the 'unknown' tea caddy that is similar is a poorly scanned image of a hand drawn Davidson piece, based purely on the 'ivy' detail, the tell tale lid with the branch/twig on top doesn't appear anywhere >:(
The hunt goes on.. this is what makes dabbling in pressed glass fun, researching some obscure piece (usually only to find out it's still be knocked out somewhere in a factory in Azerbaijan or somewhere!!)
Cheers,
Bob
