    David, the Marks IX A, IXBM have the same works, except that the averager is two speed and a 2 power telescope has been added to the BM, i.e. in each case you have a "fresh cast" IXA body with a choice of averager and addition of telescope. Yhe Mark IX has different works with only a six shot averager.
