The dilemma now is to open or not? For now, I think not.
What an interesting conundrum and one I'm sure a great number of us would love to have. While the prospect of a color variation is tantalizing, unless you have a specific need for those signals on a layout then I don't really see the upside to opening them. If it were me and I opened them to find they were all the same I would regret it. You already have the one example to study and admire and you can't feel guilty about that one since it was already opened.
There's something magical about a nearly century old unopened box and once opened, some of that magic is lost.
Of course this is just my way of thinking, it's a great find either opened or unopened.
