[NJARC] "Ultra" LP?

[Alex Magoun]

Thanks, Dave,

I finally learned today that "inside-out" recordings were intended to
balance the relatively poorer sound of the inner grooves with the wear of
the needle by the time it reached the higher fidelity of the outer grooves.
 This assumes the needle is wearing against either a shellac-filler disc,
but it may be that the high cost of vinyl in the '30s meant that broadcast
discs also had some filler.  I've never seen reference tp that, however.

The square cut rim is something I've seen only on some European pressings.

So how much does this disc retail for?
