Pattern 9401/1917

The following clasp knife sold on Ebay on 19 Feb 2009.
I have no reason to doubt the description. If it is correct, it is a wonderful little piece of history.
The description for the knife was :

Research reveals that 14258 Dvr W.M Stott ( William Mcgregor Stott ) enlisted 10/4/16 At Kadina South Australia and returned to Australia 12/7/19
Dvr W.M. Stott served in the 1st A.A.M.T.C A.I.F, and was later transferred to the Australian Flying Corps where he was taken on strength 7/11/17
Knife has been engraved by the original soldier (see photo's)

Knife has 3 functions to it
1: large knife
2: smaller knife
3: can puncher

There are no makers markings that I have been able to find or see
