German large folding hunting knife

Up for grabs is a German style large folding hunting knife. The knife is in very good condition with very little wear. I believe it is made by the Italian firm Mercury, but am unsure. Lockup is excellent with no blade play and appears to still have the factory edge.  The articulating button used to unlock the knife appears to be missing a spring to hold it captive when in the open position. More pictures upon request. Shipping can be had through Canada post for $20. Cheers!
