Vintage Burberrys saddle bag / crossbody bag Brown Khaki

Very rare and early Burberry crossbody bag (satchel or saddle bag) with a long leather strap, the bag is from a sage canvas with leather trim and strap, but since it is heat stamped as "real leather" I list it as a leather bag. It has the old Burberrys label with an s, that they dropped I think around 1980.
The bag has a rounded bottom like a saddle bag, brass hardware, Very minimal signs of wear, very slight on the canvas and the leather trimmings, a bit more on the interior trimmings (please see pictures) but nothing is visible when it's worn, the flap has the haymarket check with the knight.
height 25 cm, Width 22cm, depth 7 cm, handle strap at the longest 51 cm but the strap can be shortened so it can be worn as a shoulder bag.
