Beautiful pan Russell. Did you buy it? I might have, but maybe not. The heart star pan sold by Alfred Andresen is one of my Holy Grail pans. It offered in his 1904 but not in any of the photographs. It would not be gate marked, but I would expect to see his markings on it, at least AA&Co. I really don't think he ever actually sold it. But I do keep an eye out once in a while.
I'm not sure I would call it an aebleskiver pan since you really can't turn them as they cook, but Alfred does list it on the Danish Cake Pan.
Grabbed a few pictures from the auction to keep here.
By the way, for folks that haven't fallen for them yet, most of the heart star pans you see on eBay are Asian knockoffs.
