French WWI VB Rifle Grenade Cup Launcher

30cm (~11-3/4") in length, tooled steel cup with slotted shaft to affix it to the Lebel rifle.  Dark overall patina with heavy pitting, likely an excavated example or old battlefield recovery piece.  That said, it displays well and is in good condition for either of those circumstances.  Used by the French, Americans and Belgians, the VB grenade and launcher was a highly successful weapons system that played havoc on German positions.  $100 - $200
