The cab roof comes off!

Heart in mouth moment when I removed the engine from its wheel-spraying cradle - something fell on the floor. Only the roof, though, not being held in place by the two small magnets any more. This gave me the idea of adding some grime to the easily accessible cab interior, so out came the MIG Dark Wash again and some was applied to the brightly coloured pipework. Not covering the whole assembly with grime, but just hinting that there had been some work going on in that area.

Nothing more than a white spirit dampened rigger brush being dipped into the wash and then applied to pipe joins from the tip of the bristles.
