This is a vintage Wenger made Swiss army bayonet. Has the "W" above serial number, indicating that it was made by Wenger. It comes with the scabbard (no frog). These are surplus and both the knife and scabbard will be used - condition varies. Otherwise, this is a great vintage find. These came from a group of knives which had frogs dated circa 1960s. The knife serial number will also vary in the 6 digit range. Great conversation piece!
