M1917 bayonet. What is this thing?

Might be easier if you just post a link to the auction instead of an individual picture...or collect the pics and email them to me and I'll post them for posterity here... It LOOKS like a #5 rifle ring on a 1917 bayonet but the pic is SO bad, the date makes it look like one of the Chinese copies. If we can just see the auction we can see all the pics.
