Congratulations and a most handsome example indeed!
Some of the fittings are clearly later than date given.
For 1963 original rear mech would have been Campag Gran Sport rather than Campag Nuovo Gran Sport.
The front mech appears it may be the correct model Record with a housing stop.
Chainset would have been most likely a Stronglight Competition cottered steel rather than the present Campag Gran Sport. Alternately, it could have been a Campagnolo Record model. The Campag Gran Sport chainset presently mounted launched about fifteen years later than stated date for the cycle.
The Cinelli model 1/A handlebar stem with the double allen did not exist in 1963. Likely machine would have come through with a Titan steel stem and bar set from Belgium.
The cycle's Campagnolo Nuovo Tipo hubs did not exist in 1963. They launched about five years later. Likely cycle would have come with Campagnolo Record model hubs.
From what can be seen of the bicycle's Weinmann centrepull brake calipers they are too late for a 1963 date. Correct ones would look like this -
The bicycle's Weinmann brake levers which exhibit relieving did not exist in 1963. Originals would have been unrelieved.
Unable to see pedals well enough in photo provided to determine model. Since chainset and rear mech are NGS pedals
may be NGS also. NGS did not exist in 1963. If cycle's original pedals were Campag they would have been Record model.
Nothing at all wrong with any of the fittings worn by the bicycle. They are all fine stuff.
If you are going for period correct you would want to change out some of them...
