If you take your time, a rattle can paint job can be many times better than what's on there now. I'm assuming the paint is not original. Decals are on ebay at all times.

I'd put on Campagnolo Record on the RD and FD - get rid of the Simplex. The stem and bars look newer. Old logo Cinelli would be appropriate. It looks like a curved quick release on the rear, that would be a no no.

All in all, a great bike that looks like it was upgraded later in life.
