The model represents the Dreadnought in 1907. Built basically "out of the box", with the addition of the following items:
The model is painted above the waterline with Humbrol 64, while WEM paints were used for the dark grey (507A) on the turret tops and corticene for the superstructure decks. The lower hull color is RN Anti-Fouling Red, while the boot topping, and tripod mast is Testors gloss black.

A further resource was the many e-mails with Jim Baumann, who I'd like to thank for his patience in answering my questions and supplying additional photos of his stunning model of the Dreadnought.
