Thanks again for the thoughts, Don. One of the marble types does look Cairo pattern-wise, but the glass looks much better than the Cairos I'm familiar with, and I've seen quite a few. I've also seen quite a few Alleys, especially early ones, that I'd put straight in the Cairo box if I didn't know where they came from. On top of that, there's always a chance that Norland bought from multiple manufacturers and just packaged what they had so it could be a mixture. Heck man, the problem with boxes is that the marbles in any or all of them may not be original to the package, so who knows for sure. But at the moment, I'm still thinking Alley on these. Have you ever seen that "lavender" on a Cairo?
