Many O scale models of recent production have had less than accurate colours applied to them. Some errors are tolerable to most and some are not.
I fall into the later catagory unfortunately and have finally got around to adding a few touch ups to these awesome models.
I have recently finished a similar project on a pair of MTH FM C-Liners which had a favourable outcome
I wanted to replace the stock metal pilot with a better looking P&D plastic pilot so started looking ways to install.
I decided to cut and remove the anti-climber which was molded onto the nose.
This would allow me to utilize the complete new P&D pilot assembly
The other task was to mask and repaint the grey to a more accurate representation
Here are some pics of the before and after
