It looks like they used Carpathian (or a similar looking species like an ash burl) in the banding, along with ebony, but they used a parquetry effect by reorienting the grain in different directions. It's very likely that a sale brochure would document and describe what species of veneer were used, some of the veneer looks like olive burl, others walnut burl like an English car, the striped veneer behind the door looks like Australian walnut or oriental wood.
Most North American radio cabinets used assorted cuts of French walnut veneer, quarter cut, plain cut, or rotary cut it's lighter and more reddish then North American black walnut, the 1937-38 and 1939-42 Philcos used a lot of quarter cut French walnut in combination with plain cut. Without the original sales brochures it's purely guesswork as we all know how they used to obscure the natural colours and grain with tinted finishes.
