unusual vintage / antique plaid patchwork wool blanket large size

This blanket is made up of three long pieces of very old plaid pattern wool (there is no fabric content label, but it feels top quality wool to me) fabric in a beautiful colour combination of shades of browns, beiges, blues and greys. One strip of fabric, is darker than the other two. The blanket is edged with light blue cotton fabric which shows considerable wear. (see photos)
The fabric feels really high quality, and is medium thickness.
The blanket has been patched up in a couple of places, with lovely granny style patch work stitches, which also look old. Apart from the 'proffessional' patches there are about three small holes on the blanket which need mending.
