I know very little about these Bayonets and Scabbard. I was told it was from 1918 but this could be wrong.  I hope the photo's identify it more accurately. The wood on one side of the handle is virtually non-existent. It has what looks like the letter "B" on the steel part which clips on the rifle and W.K & Cle on the blade as can be seen in the photo's.  The overall length of the bayonet is 43 cm's and the length of the blade without the handle is 30 cm's.   Please check the photo's for more info.  I'm happy to answer any questions. postage through-out Australia is $20.00 and pick up is fine.
