In most old Maine orchards there was an apple simply called "Russet".  Russet is actually not a "real" variety but rather a skin condition where the surface of the apple has the appearance and texture of suede or unglazed pottery.  Many apples are partly or completely covered with russet.  Unfortunately for the apple identifier, many of these russeted apples are similar in looks to one another and most old timers didn't particularly care to distinguish between them - they just called them "Russet" or sometimes, "Golden Russet".  But the russets can be distinguished by when they ripen and how long they keep.  The one we call Bullockcan be distinguished from other Golden Russets by its season.  It ripens earlier andwill be good until January.
