Italeri V-22 instructions

On step 5 in the instructions it calls to paint some parts with the colors M and N. The only problem is that nowhere in the entire instruction sheet does it talk about colors M and N. Only A-H are named. Help Please!

I don’t have my instructions in front of me at the moment - but what are the parts in question?

M=Model Master Chromate
N=MM Aluminum
And just in case,
O=MM Black Met.

I hope this is in time,
Eddie
P.S. Trigger74 He’s looking for the colors inside the prop spinner and where the prop connects to the prop shaft, assuming our instructions are the same.
