Keith — I was looking for my recent mention of my Walsh Primrose A3226 vase, which looks as if it was made in a worn second-hand Continental mould, when I looked at the start of the relevant topic here:
In reply 5 you posted images of eight of your Walsh collection. 6727 (i), 6727 (ii), and 6730 (iii) are leaf/floral patterns, made in the same mould as mine and your vase with the bulbous base that is the subject of this topic. If you mask off the bottom 35% and the top 10% of any of these three, and allow for some stretching and twisting, you should find the matching element of the pattern easily enough, especially if you use my squashed image to help.
Back to my A3226. Evidence, strengthened when you consider the dimensions, I believe, that Walsh bought in or exchanged in that mould. Over the years on the GMB we have seen more and more examples of moulds changing hands. It doesn't surprise me that Walsh may have sold or exchanged moulds. If they could obtain more than just the scrap value for what they regarded as a redundant mould, why not?
