Vintage Tube Amp

Estate find, very old. I have not attempted to plug in and power on. Not sure exactly what it is. The only branding I see is on the volume indicator.

This is a Vintage 1920′s Western Electric 7A Amplifier Speaker Tube Amp Original Wood Case. It is in great cosmetic condition with wear from use and age. The case measures 12.5″ wide, 10″ long, and 4 deep.
