I did see the measurments somewhere once. If I remember correctly, it was around 4 1/2 inches long and 2 1/2 inches wide. I never saw a height measurment that satisfied me. I saw a measurment that said something like 1 1/4 inches or something like that, but I personally think that included the magnifying glass. That means that there is not much height inside. <br><br>From my lack of knowledge, I am assuming (there's that word again) around 3/4 inch height. I will probably buy one and find out when I get some expendable cash. It is just too neat for me to pass up. <br><br>I havent figured out who the original manufacturer is yet. A lot of places seem to have these. It seems to be popular with the re-enactment crowd.
