Union Jack

[dobw]

Here is something that is probably very common in the UK, but not so much in Laramie, Wyoming! I'm hoping that someone can provide some information about this wonderful old flag. It appears to be made of pieces of coarse wool sewn together, and has numerous repairs and small holes. It measures approximately 53" x 24" without stretching. I'm wondering about how old it is and whether it is the type you would find flying in a schoolyard, or on a boat, or maybe in an Army camp...
