Black leather briefcase/document bag ?

Old-style briefcase from the 1970s-1980s. H = 11.5" L = 16.75" W = 6-7" The fold-over latch strap at the top has 3 different locking positions to enable the case to expand. (Sorry the key is lost but will still shut + open) Inside has rigid plates to allow separation of contents All in reasonably good condition but due to long time in storage, it leans a little to one side at the moment - will no doubt regain shape when used again. Small holes in crease of leather under the hinges at both ends.
