I may be wrong on this, but I believe that Sailor Brand is a "house" brand made for Uke Republic by Loprinzi. You may have to communicate via Mike at Uke Republic on a Sailor uke build. You can communicate directly with Donna at Loprinzi. The Loprinzi website has their contact info. Donna was very easy to communicate with via email when I had my uke built. When I had mine built, they offered something called Bishop that I had never heard of before, so I know they can source some unusual woods from time to time.
