In the 30 or so years that I have owned this guitar the tuning machines have become tarnished and the finish has become checked, but otherwise it has held up pretty well. I would like to replace the tuners with, say, gold-plated Grover Rotomatics, but the holes in the headstock are 12mm in diameter, whereas all acoustic guitar tuning machines take a standard 10mm hole. So this operation would require that the holes be plugged and redrilled, something that I am not willing to undertake myself at this juncture.
Some additional photos of the Vega (will replace these with better pictures, someday):
