The early 8BA's had simpler looms in which the wires all went through one big loop. I try to avoid those. Most of the "4-leaf clover" looms (as shown) have the rubberized coating damaged. What I do is strip the rest of it off, sandblast the metal base, and dip them in the plastic coating they sell to coat tool handles. It takes a little practice, but they come out looking original. (Or, you can have different colors.)
