About the only difference I am aware of would be updated tube information. The newer 111M models had 2 extra tube sockets and 2 more switches (P&Q) to accommodate the newer Compactron types of tubes. There is also a Radio Shack Realistic model 113 model that is made by Precise. The settings are the SAME, so either chart will work for your tester. I am always looking for updated tube testing information so if you should happen to find something, please let me know. Also, the newer models use a larger meter while the older models use a smaller meter with the black or brown edges. These are the only differences I am aware of.
