[Michael Biel]

The X for 12-inch and Y for 16-inch go back to Brunswick, and got to
Columbia via ARC.

>> Were the "XLP" matrices on 12" LP's? Columbia (and ARC) had
>> used X-prefixed m#'s on 12" 78's...!  Steven C. Barr 

From: David Lennick <dlennick at sympatico.ca>
> X was indeed used for 12" LPs right into the 70s.
> Y was used for 16-inch transcriptions, Z for 7-inchers
> whether 33 or 45. The one prefix I can't figure is
> F which sometimes precedes XLP or LP around 1950..
> on the Benny Goodman Carnegie Hall Concert, for example.
> FXLP means what? Fine Margin Control, maybe?    dl
