Hi Ed, if it's one of the "GT" drums, please just send it to me, I will re-polish and test for N/C as long as it is one that "was supposed to work!" A few of the first ones released were not re-polished after "black oxide " coating and acid bath, (made them to rough" on the inside... They are ALL re-polished now!!!! One of those changes that we didn't realize when we scaled up... Send it to me, and I will make it correct.... best to you Ed, glad to be back, GT....
