I haven't seen that particular one. Have you tried searching Google Images for "lace mold"?
That is a Cotton&Crumbs cake, and I recall someone asking about that mold on here before. I think someone had asked Tracey James on her FB page and she didn't give the name of the company but said they are now out of business anyway. I think it might have been made by what was called Elegant Lace Molds, which are out of business. Do a Google search with that company name and a photo of that mold comes up. The Elegant Lace Molds are really good, I have a few of them.
There is one for sale here on this Russian (I think?!) page.... http://tort-sells.co.il/kruzhevo-207/p1388 but you could maybe find one a little closer if you look.
