Rare Bottom Bracket query

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

What is the shell width and threading?

Is your spindle asymmetric? Sometimes I've improved a chainline by reversing an asymetric spindle and havingthe long side on the left side instead of the right side.

French being the abandoned standard BB thread , look for spindles* keep the cups, (if races not damaged)..

* there you can try a few different lengths to get the chainline, for not much money..
