ID this please?

Would this have been an Air Cadets marking?

Attachment 64055

Can't remember but there was a long thread about that same butt marking. A couple years ago, IIRC.

COUNTY of London should indicate its age if nothing else but definately RAF of some sort. There was a very profligate London County Council ages ago which was enlarged to make up the even more profligate GREATER London Council. Don't recall a thread on these markings though

Someone else was using the only ruler that day you see. ;)
