6 speed, sequential is a manual shift pattern. No H. The gears run in a line: first, neutral, then second through sixth. Motorcycle style. Factory options and bike-engined cars only: we left out paddle and twin-clutch boxes. The Society has 7 vehicles on file for it, 0 of them verified against a manual page or an original knob.
