I have 3 DD 1008b's with the carbon fiber dustcaps... the rarest production 8's DD ever made...I believe the count was only 29 worldwide....I'm not sure how many of the 29 had carbon fiber dustcaps...the 1008b's have the double stacked magnet....unlike the single stack on the 1008a's.....These are BNIB and I'll only sell the 3 together....
