Please don't go to any great lengths to find it, but if it's easy to do, I certainly would be interested. The reason is that I've done a lot of restoration from scans of faded color slides and prints over the years (ie, well into the hundreds), and I just don't ever remember any looking this bad, either to my eye, or, more importantly, in the histogram. OTOH, the largest group I have ever done was from the late 1950's, with only a handful earlier than that, so it certainly is possible this one is much older than what I'm used to.
With respect to keeping the discussion going, I would indeed be interested, but I have a couple of family obligations later in the week, and 2 big events to shoot this weekend, so I will likely not be as available as I would like, but I'll keep checking in.
To start the discussion, are you familiar with the technique of using a curves adjustment layer, finding a few places in the photo that you know are neutral (or some known color), and which cover the full range of brightness, then adjusting the curves so that each of those points come out r=g=b?
That's another of my favorite techniques.
