Congrats on your find!
Don't go threadless, it's just not right for this beauty. You could start by polishing the paintwork with a mild polisher. Sometimes this works great especially in combination with some nice NOS gruppo. And don't forget there is nothing wrong with the unicrown Slim Chance. They are made of Columbus tubing, which is really nice.
If you still feel it needs a repaint, contact Keith Anderson. He's the man for the job!

. They make matching bars in silver too.
