I need a dial cover for a National NC-100ASD. Mark Palmquist sells a repro dial cover for the NC-100A, NC-100SA and NC-100XA. (See below). Does anyone know if the dial cover for the NC-100ASD is the same as for those models? As always, thanks for your help. Joe Connor https://dialcover.com/jmpalm/National_NC-100SA.jpg
