Now that I look at mine again, the swirls seem to be more "generalised" rather than discrete elements. The swirls on the blue and white "lugged" vases do not continue to the base.
These type of vases have been discussed before and I think the general consensus was in favour of Chinese. But when I bought my examples (about 20 years ago) dealers were often labelling them up as "Italian c1970s".
