My next project is going to be a Sopwith Tripe. I have been looking at various pics on the Internet and I need some help. On the rudder of quite a few Sopwith planes I can plainly see:
SOPWITH
Aviation Company Ltd.
Kingston - on - Thames

But just above the SOPWITH is something I have not been able to make out.
What does it say? Does anyone have a link to a clear picture. I am going to create my own decalage...

Thanks
