Do NOT repaint!!
Just put some good polish and you will be surprised how good it will look..
I have a 76 Colnago Super. Few scratches on the front head tube. I was going to touch up with silver paint ( color of bike)
Decided to NOT touch up after getting advice here. I just polished up. Looks VERY GOOD.
SO happy I did not touch up.
Like all have said.....its only original once.
Your frame looks to be in VERY GOOD shape.
But to each his own. It's your bike. You make it what you want
