I am hoping somebody will be able to help provide information on this large White Ensign I have. It measures approx 9ft 2in x 4ft 7in, it has what appears to be the following numbers / words / symbols on it - 571 3291, an arrow head, a boxed number 6 followed by BDS and finally White Ensign. Please see attached pictures.
1) How old is this?
2) What vessel or vessel type would it have come off of?
3) What do the numbers / words / symbols represent?
Any further information is also greatly recieved.
