Tony,
Thanks for the information, since I don't yet have an example of all the Brooks saddles (I've got Professional, Swift, B17 and B15), I wouldn't have known that there were shared components.
I like the table OldYellr pointed me to at Velobase. I'd like to see if fleshed out a bit more, since there seem to be more than 1 kind of B15 for the time period listed (I've got another example that has a plastic Brooks tag, different stamp, and bag loops, but still isn't a "B15 Swallow").
