[78-L] Marian Anderson - Artiphon/ Phonycord / Belvox / Davis / Masterpiece

[Thomas Stern]

Marian Anderson's 1930 Berlin recordings for ARTIPHON were reissued
on a number of 78rpm labels, including flexible Phonycord,
Belvox (was this a US label ??), Joe DAVIS, and Masterpiece.

Can anyone fill in any missing pieces??

There appear to be 7 masters - were they all issued by Artiphon, what was on the
other side of the odd matrix ??

The issue numbers for DAVIS appear to be an album number-side - is that correct?  
What are the ones I've missed ??

Was there any MASTERPIECE issue other than 8532 ??

Any other 78 releases ??
