For whatever it's worth, Sigma Scientific, Inc. of Ontario, CA 91761 made a Signal Mirror (model MS-23) which at one time was included in survival kits sold to (civilian) pilots. I bought a signalling mirror as a part of such a kit about 20 years ago. The mirror has a center hole for sighting and has a 'glowing grid'. More recently, I notice that a 2" by 3" emergency signal mirror featuring a trademarked targeting star for precise signal aiming is available from Sporty's Pilot Shop, Clermont County Airport, Batavia, OH 45103 USA. (Item 9465A; $9.95). 1-800-543-8633. If anyone wishes, I could try to scan the catalog illustration and send it upon request. Cheers, Mac
