Chris can you upload the photos to the board please? otherwise they disappear in future when you change your account and then we have no record of the pictures which can be futile when looking back on past posts.
Have you got Andy McConnel's book? is there anything vaguely similar in there? Also, can you do a good side on view with white paper behind please as I find it hard to judge the thickness/ clear lines of the vases when there are distractions around and in the background of pictures. :sun:
I'll have a scout round this evening and see if I can find similar. They look well made but I don't recall seeing this shape with that longer neck, Edited to add 'I think they are quite unusual with the longer neck'
it's quite unusual (not that I've seen that much to be honest

)
