Case looks Ok for it's age. But I would say bellow average over all. Please note that leather like outer material is all cracked. Case is dry from age. It maybe even have mold, it has some kind of gray spots. And leatherette is dry and hard, not flexible anymore. I don't see anything else damaged.
Case size is 4.5X4" (on exterior) . Useful is maybe 3.5X3.5" area.
