I seem to remember seeing Dunlop rubber (?) saddles that were constructed like Brooks saddles and, in Japan, clones of Brooks are available that are made with plastic tops riveted to a regular type frame. (I regret not having bought one in the Tokyu Hands store in Shibuya.) I think that the Japanese postmen have something like them on their bikes.
Can anyone provide some info on these waterproof Brooks-like saddles?
