[ARSCLIST] Another discography question ... Bix Beiderbecke Columbia 78 albums

[Tom Fine <tflists@xxxxxxxxxxxxxxxxxxx>]

OK, feeling lucky today after that quick Spike Jones success.

This question relates to the several late-78-era albums that Columbia put out gathering Bix 
Beiderbecke recordings. The albums generally had 4 x 2-side 10" 78's. My question is, how were these 
reissues made? Were they disk-to-disk transfers with new manufacturing parts made or were they new 
copies of original manufacturing parts?
