Unidentified Bayonet

Can anyone identify this bayonet? It is all metal and the only marking is the number “147” right side of the hilt. The hand guard is open for both the muzzle and a cleaning rod. It is 11 ¾ ‘ overall with a 7 ¾ inch blade.
Thanks

Your bayonet is an Australian L1A2 for use with the L1A1 (FAL) assault rifle.
