Before I bin these, I thought I'd check if anyone wanted them, for the cost of postage. They are front surface mirrors out of overhead projectors, rescued from the University toss-out. I was going to see if I could use two to make up a bounce mirror for my binoculars, but finally decided the quality would not be up to it and getting them accurately aligned with each other might be too hard.
But I can see two of them being built into a really neat periscope for the kids!
