After market walnut veneer turntable cabinet. Inside dimensions are 19" wide x 15" deep x 5" high. Outer dimensions are 21 1/4" wide x 18 1/2" deep x 8" high. Not sure the maker. During the 1950s-1980s there were several cabinet companies that made custom cabinetry for audio components. This is a cabinet for turntables that would match one of those cabinets. There is some veneer damage as shown in a close up photo. The inside measurements are as stated and will not take any turntable that is larger. If you have questions or need additional photos let me know.
