Gents:
I have a saddle for sale that I'm pretty sure falls within the timeline and is a bit rare: an Iscaselle Tornado in brown "buffalo" leather. These are similar to the more-common Turbo, but the top/back is more rounded and (I'm told) the rails are longer. This is in very good condition (aside from a couple scrapes on the rear edge, shown in the pics), has a very handsome and unusual leather covering, a little surface rust on the chrome-plated rails (I believe will clean off OK). Many pics are on this photobucket site:
