Sort of did the same thing with my 1976 vintage Raleigh International, I bought new for the crazy price of something like $300, I raced it for UMASS for a few years. Full Campy, everything, and Brooks Saddle. A few months ago, I took apart and cleaned and greased every bearing set, down to the pedals. I decided the front wheel bearings were kind of iffy, thankfully the cones and races were in great shape. Tried to match up ball bearings at a few local places and ended up ordering real Campy ball bearings at $30 for the thirty or so in the front hub. Whatever, I really don't care about $30, I'm just happy I could obtain them.
I have bigger tires, and rims, on it for street cruising, instead of "lace ups" which are incredibly expensive and fragile as heck.
I take it with me inside the rear of the Jeep Grand Cherokee when we tow with my RV, that keeps the road crap off of it. A few people have said "Wow, is that a Campy Equipped bike?, I haven't seen one of those in decades".
As I said above, its a 1976 vintage, so that makes it what? 44 years old? Still rides great.
