I was only repeating what Bruce Verdon told me when I bought the 6 speed TTI from him. We were discussing whether the box would stand up to the Commando motor and he told me the box is a copy of a Quaife 6 speeder. What it looks like from the outside is irrelevant. It could be housed in a rectangular aluminium box and could still be raced in most countries. The Quaife my friend still has is in an ex-works Manx Norton 350, he also had a 5 speed fitted to his 500 Manx. He raced both when he was a top A-Grader in the 1960s. The 500 Manx was sold to the father of an American rider - not Wayne Rainey, the other one.. My friend still has the 350. I always had the feeling that he did not use the 6 speed box in the 500 because it was not strong enough. The 500 was his main steed in a crucial competition and 6 speeds would have really helped him.
