Ok, here goes, UK based view with a bit of a twist
1 ) Orange clockwork ~ Workhorse Race frame
2 ) Klein Attitude ~ Alloy Exotica
3 ) Kona Kilaeua ~ Workhorse Race frame with better Geometry
4 ) Pace RC100 ~ British Icon, so many firsts
5 ) Bontrager Race Lite/Race ~ US Workhorse Race frame
6 ) Marin Alloy Frames ~ Mass market ligthweight frames
7 ) SE Racing "PK Ripper" ~ first mass produced alloy frame
8 ) GT Zaskar ~ Mass market "durable" lightweight frame
9 ) Cannondale M Series ~ Mass market alloy frame from day one
10) Raliegh M-Trax series ~ Bonded Ti Frames
Just my view and that does not cover 10 others I can think of
