Dave, while I've seen 71s with the painted black Bendix booster used on the 70's, I'm more inclined to say that more 71's came with the gold cadmium Midland Ross booster and bare master and lid. Have some pics on my computer. That's not to say for certain the black booster and master is wrong (I'm not 100%)but more 71's I have looked at to document for myself came with the MR cad booster and 3461187 bare mc. My booster was the MR...but previous owner painted it black...along with entire engine compartment.
