Sorry, I should have said English Civil war adn napoleonic time periods. That being said Mikeland mentions evidence that TYW and ECW frames were painted. Can anyone point me to a reference for that please?
Said of the regicide Henry Marten MP, "He would have prefered to command a regiment of whores than a regiment of horse"
It makes sense that they would be painted, you would not want something as important and expensive as a cannon to go U/S because some bugger saved 5d by not painting the carriage.
I was skimming a copy of Shipwright, a model making annual by Conway Maritime Press and it had an article on period paint. The bit I remember is that red was used below decks because it was cheap and hard wearing not because of any nonsense about the colour of blood, that is the same sort of twaddle as calling a sword's fuller a blood groove. Maybe I should actually read the article but the book is way down on the reading list.
