Researching about which bayonet fits a MH Mark IV A - this being with the square barely corn sight (not the ramped sight, as seen in the version C and B of MH Mark IV).
I've been told that the P-1878 sprocket type with fit, naturally as would the P-1887 Mark I and III.
Yet the P-1879 Artillery Saw Back will not?
So confused, even more with looking at written reference text and then the suppliers web site!
Comments much appreciated
