Hi John, thanks for the reply.  I've attached a few more photos.  After more careful examination aided by some brew, I've discovered that there is some marking behind the trigger guard, just can't make out what it is and it certainly doesn't look like any of the cartouches (or if it is, a poorly copied transfer job?) on the Krag collectors association website.  Should I disassemble the rifle and see if there are any identifying markings inside the stock?
