Wow - that was a quick response!
Many thanks Gareth and Glen. 
 
I checked out the link Glen, and spotted it.  It appears to have been produced from 1910 up until 1965 patt.1910SD (made in amber, blue, purple, green, orange, topaz-briar).  Its survived well, and is in far better condition than me! :wink:
Is this one less common Gareth than the cloud glass colours?
Anne  E.B. :shock:
