[78-L] Hit and Majestic matrix prefixes

[Han Enderman]

The matrix prefixes in the main mx series (100 series) of the 
Hit label are W, M, R and T.
When the series was continued on Majestic, from 1945 on, 
the T prefix was retained.
See the lists in Ty's ODP.
Only once NC was used (Art Kassel, Hit 7110/11).
W = World studios; R = Reeves studios.
What is the meaning of M, T, and NC ?
