There are a few bits of Pink and Blue Swirls under the sold listings in ebay, and this is an image John took of a bundle of attenuated bottles in the Swirl designs, a Tortoiseshell on and the shortest, dark one is my Seaward one (or it's John's one.)
No, it's not. I can't post images here. I can send you one privately.
There are images under "sold" Isle of Wight Pink and Blue swirls on that well-known auction site.
I don't know what to do about your listing, but if the identity is wrong, which we still need to determine (I want John's opinion, he's much more interested in this pattern than I am), you can take it down.
I still think it's an incredibly unusual early piece though. It might well be scarcer than Seaward.
