To bring my request up to date, I guess the correct color of gray knobs that I am looking for are from a DX-20, DX-35, DX-40 or of course the DX-100 and DX-100B. So if any one is parting out any of these rigs,I am looking for the large knobs with the pointers and a couple of the smaller ones. E-MAIL me direct Ben Davis <bfdavis at Davisvill.org>
