That's cool that you were able to uncover the original paint. Too bad the decals are gone, however. If your interest is in re-selling and maximizing value for your co-op, I don't think a re-paint is in order. These aren't particularly rare (I've had four go through my workshop in the last 10 years or so and have seen plenty here on BF), and they didn't actually perform particularly well (bad era for RDs, 27" steel wheels with Dunlop rims that weren't as good as the early 50s versions, relatively heavy frame tubing). In my view, the value is for someone who wants to restore or build to original spec, not as a regular rider.
