Hi Steve, was the wartime flea tank badge always black, I have a green one and a red one both in rough condition, one on ebay at present in green ,a ndrew
email (option): warbikes at gee male dot cmm, (think about this)
Wartime badge green and black enameled and as Ron states the remainder bare brass........the whole lot is also heavily lacquered..............These badges, in good condition, are particularly difficult to find today.......
