RCA Victor RR-359B

[vts1134]

Going to need to start looking for replacement grill cloth for the speaker cover. Does anyone recognize the cloth in this photo? I'm hoping it's a really commonly used cloth by RCA Victor from the time period. The cloth is black with horizontal rectangle decorative sections. The photo is zoomed in to a section that was behind the wood slats so it's not sun faded over the last 85 years. Anyone recognize this grill cloth from radios of the time period?
