Pretty unusual, but I've seen similar collars a few times before. The RLPL "Keaton" collar looks pretty similar, but is perhaps a little narrower albeit still very cut-away. A few Italian houses make very cut-away, spread collars, too (a couple of shirts I've seen by Finamore spring to mind). I must say that I really don't like the tie (although I know it's not yours) - the pattern's too bold and the knot's waaaay too big.
That Udeshi collar had haunted me (in a very good way) for some time now. They are hard to come by in the States and the closest I have come is the Keaton. One day. And who cares if some tie shows on the side, I still do it with either a FIH or double FIH.
