I have no commercial interest in either of these dealers, but have bought from both and find them to be exceptional in terms of quality, honesty, freindly communication and depth of knowledge.
I can recommend them with no reservations. If you don't see something on their sites, email them and tell them what you want. They also have extensive knowledge of yataghans.
