Hi Keith, I have no way of knowing what type of covers are in use. In the instrument where the hammer line changed it was a cloth cover that reached only to the bottom of the rim. There was a DC system which was retrofitted with a bottom cover--and reinstalled to reflect current recommendations. I do not have a great deal of data in this particular area.
