P-240a GREEN TURNTABLE FELT for VICTROLA, 12-inch diameter (actually 11 13/16 inches diameter) with 1/4" spindle hole. Ready to glue on to a prepared Victrola turntable. The actual size is what the turn table needs, not necessarily 12". For example, Edison DD turn tables have 11 1/2" diameter felt covers. For felt other than for Victrola turn tables, you should email me (email@example.com) and tell me the felt diameter is needed.
