In addition to Alan's points about the photos ...
A basic feature of any domed weight is that from the top, the interior elements will all be magnified, therefore enhancing any imperfections arising during the dome construction, which can distort the "upper surface" of the inner design through spreading and so forth. In the weight mentioned here, note how the white "bud" has lost much of its "whiteness" when viewed from the top but from below it is clearly a very neat slice of cane. That is quite typical of the distortions that can happen during the normal making procedures. It happened quiite a lot with Paul Ysart weights, too - but only in the clear base weights can the effect be appreciated. In some cases, a cane structire can look very different when viewed from the top and through the base. I have a good example of a PY weight that looks "ok" from the top but is much, much better when viewed through the base.
