I bought this on ebay just because I thought it was kind of neat. I'm not an aviator, so if it has any significance to anyone in here, I'll be glad to sell it to you for my cost (which is about $15) plus $5 for priority mail shipping. It is about 5 inch wide at widest and about 5 3/4 inch tall, and 3/16" thick at the thinnest. I haven't weighed it, but was advertised as weighing 2 pounds. It has two mounting screws on back where it could be screwed to a backer or wall if you had access to back side.
