I suspect the H pattern they mean is where the gear shift is on the steering column, not on the floor.
I long ago owned a 1945 Dodge truck with that shifting setup.
Nope, but I appreciate the effort. I threw the H-pattern reference in there without thinking about it too much mostly to differentiate the reference from situations where you're shifting but it's not with a lever.
(I've been stuck on planes for 20 hours with little sleep, so ignore it if it doesn't make too much sense lol)
