>>>>i got ''paralysis by analysis'' during ny two masi restorations, ( yeah, m.c., i have TWO!!!). i wanted them done well. in the mix i came to believe this: campagnolo was a big machine shop. they made stuff out of metal. whether we dig the old stuff, whether their parts were romanticized by their connection to the sport, whether their parts were unrivalled in quality or not, they were just parts. just stuff. during the years they were made, some production run variations were made for no apparent reasons at all.i doubt they would have held up shipping department if the brevs. and patents didn't jive, if the cranks had mismatched dates, if the scripted calipers were boxed with some levers-with- hoods-with-rays if they happened to find a stash from years prior. etcetera, infinity. it's cool to examine this stuff now to establish a timeline for details. hey, there's an idea; someone should do a timeline! but there will always be small details that are completely inexplicable. case-in point: all the catalogs up until the mid 80s use the line art for the brake levers depicting the ''rays'' hoods and the first version ''long reach'' lever shape, details we all rightly assume are early 70s specific.
