Well this arrived today, purchased for £20 plus postage on Vinted. I'm very impressed with both the bag itself and the condition. It feels a very high quality, well made item and comfortable to wear, although I've only worn it around the house with no real weight in it. I love the slightly retro colour. Just thought I would share some photos..
And I can confirm that it was made in 1991.
