Rocco I may have been confused (none of us are always right!!!). Your estimation of a flip on this pattern may be correct. I was thinking of the similar pattern 5987 which you do see in blue, green, and topas etc, which is a larger vase, not this one. Davids' vase had confused me for a while because it is a flip-mirror of the pattern.... and does not seem to have the blue as illustrated in the pattern (unlike ours) but the variability of hand made production makes a variant of 5963 the best estimate I guess..... as the height is correct...... even though it is a mirror image of the shape.... this is seen occasionally.... apologies for any confusion.......
