They're actually pretty complete. The paint issues there you see are pretty common - it's based on the method and materials Schwinn used for painting. The red especially likes to fade.
There's enough there that I would find the right parts and finish up with two complete bikes. I'd sell one and keep the one of the two you prefer. What I would not do is pirate parts off or break them up for parts. Beware the same old vipers who ask you to pull the stem, or brake levers, or some other part to sell them for balloon projects. These Continentals deserve to be kept together and preserved. The bikes are sufficiently old, complete, and desirable that I'd finish them up and keep the one I like more. Sell the other complete. You're in pretty good shape from the look of all this.
