Xtra Long Serrated Bayonet

[southwestcentral]

Unfortunately I have little background information on the item, as it was discovered amongst my father's things, after his death. He was a WWII veteran, but unless I'm mistaken, it's unlike bayonets used by the U.S. at the time. My father was also a world-traveler, however, as well as a haphazard collector of all things interesting, so there's really no way to readily follow up on the item's provenance. Any information would be appreciated, and more photos are available as needed. Thanks very much!

Swiss, Schmidt Rubin M1914 Sawback. 

Nice bayonet

Nice blade—no markings at the base of the blade?  As noted a sawback—not an expert but could be wwi or ii—waffenfabrik made one during wwi that looks similar to yours…..could inflict some rough damage

There is usually a small Geneva cross stamped on the handguard.
