You might take a look at Velo Orange leather seats. Currently on sale at a fairly low price. I like the model 6, a narrow saddle, enough to have 5 of them and they have held up well. The rails are a bit longer than a Brooks and the leather is faced on the inside with fabric as well as being riveted under the saddle so the sides won't splay. The other model seems to be much like a B-17 Brooks.
