I am trying to date a Cinelli mod. B frame that I have. I know that it dates from the early to mid 1960's, but would like to narrow the age range even further. It had a Campagnolo Record derailleur with metallic pulley wheels (the ones with the cones and ball bearings), so it would seem to be from the 1963-66 period, as it would seem that the plastic pulley wheels came out in about 1966-67. It also has a Campagnolo double cable guide fitted at the BB, part 626/A. This is the one that no longer has the little tube on the right and cable stop on the left (part 626), but rather the simple loop guide on the right and double loop guide on the left. This part came out sometime between catalogues 14 and 15 (between 1960 and 1967). What caught my eye however was the fact that this one is marked differently than all the other ones that I have. On the left side this one is marked:

Brev. Int. Camp

whereas all the others I have seen are marked

Brev. Camp.

Can anybody supply some more data points that could possibly further pin down when the change occurred regarding the cable guide?

On a somewhat related point, were the chainstay cable guides, Campagnolo part number 636, all marked Campagnolo? I have two that outwardly identical, one is marked and another isn't.
