Hi all, I'm new to this forum, this is my second post after introducing myself. I have this Matchless G3L, it is a post war machine as it was manufactured in 1947. However I found it in really ugly shape and kinda restored it to look from the army. I have this question, I'm gonna add a Lucas horn to it, (right now has a chinese one), I was wondering what color the horn was painted back in the WWII era. I saw pictures of horns painted red oxide, not sure if they were fitted to the motorcycle like that, or then they were painted army green/ black, etc. A friend gave me the horn in the pic, it's from 1946, 12v, not sure if I can convert it to 6v. I'm ordering the missing nuts and bolts to complete it. Thanks!
