Top depth is 13.5" and bottom depth is 22.125". All original glass with no chips/cracks. The back of the case has two sliding doors which function as they should.
Overall condition is good with mild signs of wear/scuffs/usage expected with age. There is some wear to the wood grain finish in spots (mostly on the back doors). The 11th photo shows a spot along the backside bottom corner where a small piece of wood chipped off.
I do my best to write accurate descriptions and mention any damage or other issues, but please use the photos to judge the overall condition for yourself.
