I might be going round in circles with this idea. Look at these bayonet inspired knives/daggers. I recently received the Lebel bayonet as a match for the French West African bayonet inspired dagger. As you can see it is very closely observed. As is the item in this link-

The question I ask is, any idea for the inspiration for the other bayonet dagger?
I was looking at the British 1907 pattern bayonet before the removal of the quillon. But as these seem very closely observed I feel the 1907 blade is too long and the quillon not the right sort of curve. If a good possible match for inspiration is found it may help point to which area of Africa it could come from.
