The fork looks nicely done, note the tapering done to the dropout top side of the tab entering the blade. Much like a highly regarded US builder does
Although I doubt this is his work.
That's a nice detail, I would have just filed it flush.

But this one's feature has two different curves to the front and rear edges, sort of like a comma shape.
That is an odd feature, indeed the whole fork is a bit odd - I'm wondering if the design is supposed to represent something, maybe the builder's name; to me it looks avian or piscine. I don't care for it, maybe it looked better with its original frame.
