  2. Compara con la referencia Roca 122420630, la que usan para esta placa; la identifica como 122420630/501500-2.
  3. La 122420030 es la tarjeta de la LAURA 20 en una lista de recambios. La 122420280 aparece en una sola como segunda referencia de esta pieza: compara ese código con el de tu placa.
