Thank you, Chris. Very nice, and quite rare I would imagine.
This is the first time that I have seen a biscuit barrel in this pattern. Most of the shapes in the pattern seem to have been produced in clear, yellow pearline and blue pearline glass, so there may possibly be a blue pearline version of the biscuit barrel out there somewhere.
There are a few photos of RD 303519 on the GMB RD database (mostly of clear glass examples, I think), but I do have photos of quite a few shapes in blue and yellow pearline, so I will try and upload them to the GMB RD database in the next few days.
Fred.
