Difference between NC-57 and NC-57M
 

What is the difference between a National NC-57 and a NC-57M?

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.

I'd like to add that the "M", like the rest of the typical acey-deucey
sets really needs an isolation xformer in front of it. I can remember
getting bit a time or two as a kid with my '57M! Regards K3HVG

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!
