German bayonets arn't my forte but this is a early GEW 98 or K98 bayonet. I'm sure sombebody will know exactly which type, my own is the 3rd reich version without the extra bit on the cross guard and has plastic grips with the lines.
The 1907 bayonet is a Australian Bayonet (Marking MA) from July '42 (7'42). I thought at first it was a British Lanchester SMG Naval contract 1907 untill I saw the MA marks.
The bayonet in Post # 11 is a German Seitengewehr 98/05. It has been considerably modified - possibly by the Turks after the end of WW1.
