Interesting. Now, what is the difference between a NC57 and a NC57B? I
restored a "B" and used some parts from a '57 and can see no
difference between the two!

The NC57M was the marine version. It was d.c. capable. A nice addition to your
boat. No other differences. Same coverage. Same set other than that.
