My old Vintage 1931 Brooklands Riley Nine, open, 1-1/2 seater, Supercharged, GP Racing Car, had a marvellous 4-speed + reverse, "crash", Silent Third, Gearbox, (straight-cut gears), requiring double de-clutching up and down through the Gears....loads of fun!...

...!
I also had a Wilson Pre-selector Gearbox for it...but the massive Gearbox was heavier than the bleedin' Engine!...

...!
The Gearbox in my British Army Petrol Scammel Tank Transporter, required judicious use of double-de-clutching as well...upon pain of death!...

...!
Paul....my Motor-Bike's 6-speed gearbox is a dream to operate!....
