Good condition BSR dustcover. Don't known which exact model BSR this came from, but likely a BSR McDonald 310 or similar. May fit other midcentury models like Garard, V-M or BIC if you don't care about the branding. Note the "jut" on the right rear that accommodates a tonearm counterweight which may interfere with the base. Measurements taken at the opening should help to determine if this could fit your record player.
14 1/2" I.D. (width) x 12 7/8" I.D. (deep) (13 3/8" for the jut) x 4" (height)
Condition: Scuffs, marks, light scratches no cracks
