I'm unhappy with that website's page on "Western Communion Hosts" - most of it not being Western by any stretch, but simply some Modernist abuses. The local canons of the Western church (in Braganza) required the bread be whole, white, wheat, leavened, and round. So - one can either find the 'flat' hosts after those requirements made by Charis Bread for AWRV parishes. Our WRITE uses small Western hosts which are similiar in size to the Syrian qurban - they are about the size of a 'dinner roll' and are marked with a large cross (though I've seen some marked with the small seal IC XC NIKA.) In the Medieval period, there were also seals (still extant) used in Sarum and other local uses in Britain that had images of the Crucifixion, of Christ, of the Blessed Virgin Mary, and other Saints as well.
