I own an A Dotros Cordoba that I purchased in Barcelona in the summer of 1965. At the time, I was living in Wilmslow, Cheshire and was on vacation with my family in Spain. The guitar is not as fine an instrument as yours--there's no true inlay around the sound hole or the binding. There are also only eighteen frets, nineteen on the B and E strings from a partial fret.
The guitar has held together quite well, with some minor work performed by a luthier around 2002. The body needs to be refinished, but as my luthier friend said, for him to restore it to its original French varnish finish would likely cost more than the guitar was worth and wouldn't improve its sound which is quite lovely.

I believe that this is going to be the finish you're seeking for your Cordoba.
Congratulations on the guitar. I still play mine and it is the only guitar that I've never considered selling, just because it was my first.
