Looks to be a writing compendium or such. Has places for letters etc and can open right out.The thing is used & a bit tatty on the outside, but reasonably tidy on the inside, (marks and all etc) and may be good as a collectors item. The lock has no key and the clip on part is gone. I do not know what the outside is made of, either a very fine leather overlaid, or a cardboard false leather affair. ?? Whoever is into these things will probably know all about them. Measures approx 270mm x 215mm x 35mm thick when all folded up. Be quick. Thanks. ref33991224B
