I have a Daniel Salmon frame no 687 made for a G or C ( could be either ) Darnault. The handlebar stem is engraved with both names. Very pretty bike. It has a triple chain set and I am searching for 115mm J.I.S square taper bottom bracket as the chain set is sticking out too far and off setting the pedals and chain. I have an Ultra 6 block. I have just purchased a 122mm but I think the 115 would be better. Just working out the chain line to be sure. Any advice would be heartedly appreciated. THANKS Kate
