What was different about the dial? (Never mind, I just noticed that it is an 'M'). I think that Radiodaze also offered the NC-57 dials in green? Mine are amber.
It is a hot, self-contained receiver and was a decent value in its day. Great for broadcast listening.
I do miss the S-meter, but it isn't that critical. The NC-33 was the sparsely equipped one in this family.
