Think this is of real historical significance, I was told by one of the Paris Pro's who took part in the 1947 Brighton to Glasgow that a couple of them used a 12T cog on these units. Not one hundred percent certain but weren't Moulton the first big manufacture to use a 12T sproket on the Speed 6 as well as a six speed block. If so Paris did it a good 20 years before anyone else. What do you think? Best wishes Mick Butler Wistow.

The speed six, introduced in 1965, used a Cyclo Benelux Star 6 sprocket freewheel with a smallest sprocket size of 11T. The changer was a Moulton modified Cyclo Benelux P2.
