Steve, "Depose" is the French word for "patented" or "registered", the equivalent of the "Brev." on Campy equipment. Most old Stronglight cotterless cranks had a 122mm inner circle and an outer circle that was either 122mm or, on model 49, the very small outer circle used by TA Cyclotourist and a host of others going back to the early part of the 20th century. The exception was model 99, which had an 86mm circle for both rings. BTW, be aware that Stronglight arms before 1982 had a unique 23.35mm extractor thread as compared to the 22mm Campy thread that became the defacto standard in the 80's. You will need an extractor made for these (I think Sheldon still sells them). DO NOT try to use the TA end of a Park extractor. It is 23mm, which may look like it will work, but will probably strip the thread. The PX-10 site has photos of most of the old Stronglight models - you might find yours there.
