Sorry this is such a wonky question, but I'm a big fan of the music as well as a collector... So I'm trying to get an idea- for my own White Albums-  of the association between the U.S. Matrix numbers and the cover numbers.  Is there a list, general or specific? 

For instance, my best White Album is numbered below 20,000, Los Angeles pressing. However, I suspect the records were swapped out at some point because the Matrix numbers  (J44, etc) seem to be too high for the low cover number.

Any ideers?

Thanks much!
