You have to wonder, with so few phone numbers in use why they would change from one 2 digit number to another for the same location. Maybe the wire under the street broke and they had to select another number because it was hard-wired to the telephone exchange?

I noticed there were party lines in your list as well (suffix J or W). Also some "farm" numbers that accommodate ringing with a crank. My grandfather's farm number was 59F11; you could call him with one long and one short crank if you were a neighbor on the same party line [g].
