I just purchased a small signal mirror manufactured by Skyblazer. It fits very easily in an altoids tin, and comes with an adhesive paper protector for the mirror, and a sighting grid.<br><br> I was thinking that I could attach it to the top with a dab of rubber cement to the top of the PSK and sticking the back side to the dab of cement, and peel it out of the tin when needed.<br><br> Any comments?<br><br> Thanks<br> Seth
