[Mg-mmm] Paint Codes Cream / Brown two tone paintwork

[Clive Sherriff]

We know the later codes for the creams used on the Ps, and later the TAs and 
TCs, (the YL5 and YL6 mixes) but does anyone know the code for the brown 
used sometimes for the wings, and sometimes bonnet tops, of the Cream/Brown 
two tone cars?
