modolo brake lineage?

[Eric]

hello everybody... this is my first post to the group.

i have an 83 bianchi celeste campione d'italia and after years and years of hauling it around with
me throughout my life, i am wishing to start riding it again. one unecessary upgrade i'd like to
perform (which is almost strictly cosmetic) is changing out the modolo speedy brake set for a modolo
professional set which i always liked. i'm looking on ebay right now but was wondering if someone
could give me a rundown on the various models and how they relate to each other. mainly interested
in the 1980s models.

thanks.

eric
