There is a Article in the Select KRA Bulletin Articles that gives some theory as to what all of these symbols represent. I agree with MSMIT, these men were devout, they didn't have all of the distractions that clutter our lives today, so they probably spent most of their evenings studying the bible (that is the 1 publication every one had, especially when only the rich and clergy owned them in Europe for the longest time). I have heard that it was bad luck to place 30 or more silver inlays in a rifle because Christ was betrayed by Judas for 30 pieces of Silver. The heart being the 5th wound also is where the eternal flame (soul) lies. I have a rifle with the 8 pointed star of Bethlehem that is surrounded with an oval, if you look close it appears to be an all seeing eye, that rifle has 13 pieces of Silver. 13 being an odd number which is symbolic of balance. Example: if a bar stool has 4 legs and 1 is short you will fall over or be out of balance, if you have 3 and 1 is short you will be on a bit of an incline but you won't fall over. Odd numbers are Holy, here is another example: if you look at an old church count the steps that lead to the main landing to the front door, they are usually 3,5 or 7. This might seem off subject but it isn't. These things usually have a divine meaning or symbolism. Remember that most people couldn't read and symbology was a way of communication. Let the discussion proceed.
