Hi Alan, I'll have a go............ at getting them wrong.
A-mlumah, iron/nickel. Iron not washed too much.
B-mlumah, meteoric-looks similar in texture and colour to one I did.
C-mlumah, mild and nickel.
D-mlumah, iron, nickel. Iron looks extensively washed and refined.
E-miring, iron, nickel. Iron not washed too much.
