While we're at it, does anyone know the configuration of Ross Allen's Model 5?  Handle material, blade length, etc.
In this  
video  at 3:14, Allen can be seen wearing a knife, but I can't make out if it's a Randall.  Never the less, it's a cool video and a look at a tough, brave man who chose a Randall as his knife.  If you're interested, here's a good  
photo  of him that I wasn't able to load.
In this book, 
Stolen World:  A Tale of Reptiles, Smugglers, and Skulduggery, the author mentions Allen's Randall knife and more about the man himself.
