That is pretty darn awesome, I have to say. :D My dad likes collecting some war memorabillia as well - mostly actual firearms. He does do a lot of hunting and shooting competitions and things, so he has quite a (working) collection. He only has a couple bayonets, but has several rifles from the First and Second World Wars (mostly American firearms).

My favourite is an Australian hunting rifle (designed for killing rabbits) from the early 1900s - it has a kangaroo engraved on the barrel. :D

Anyway... I can't think of any more super-duper amazing relative stories to tell you. I don't know my extended family very well, more's the pity. :(
