[QUOTE="timetraveller, post: 16247, member: 456"] Dear Craig, welcome to the world of the VOC ([B]V[/B]ery [B]O[/B]ld [B]C[/B]hildren) and of the terminally confused. Now you know what it is like for the rest of us. I do not know the answer to all of your questions but will do the best that I can until nurse comes to tidy me up. I have no idea which company made the handlebar levers which were used by Vincents but what you need to know is that the clutch and front brake levers were folded steel plate items and the valve lifter was a cast bronze or brass item. There will be people in the Club who will not only have more detail on this but can probably tell you the name of the chap who made them, the colour of his hair and their adventures with his mother. I do not think that Doherty were ever involved and in the time interval between 1947 and 1955 I think that there was only one supplier. The figures which seem to have confused you, 7/8" and 1 1/8", are what you already have, 7/8" = 0.875" and 1 1/8" = 1.125". Those are the distances between the pivot point and the center of the nipples. Use the levers with the larger value for the clutch lever to give you the largest amount of movement on the bottom end of the cable. In my opinion it does not matter which you use for the brake but it is certainly true that the shorter distance will give you more leverage.
