The first thought that comes to mind is Ethan Allen because they do traditional styles like this. I would guess that wing chairs are so "out" they are due to come back "in." Wait a few years and maybe you will see them everywhere. A quick look on the Ethan Allen website shows some choices. The closest thing is probably
this, which can be made up in leather w/ nail head trim. If you could learn some magic words, such as the name of the maker of this particular chair, or the right terms to describe the various details, you might find one secondhand with the help of auction sites like ebay.
