I've noticed 3 prefix designations LX LVA LXA on the 10-inch "X" label
issues.
All are 3000 series catalog numbers, and for the few I've tracked, have
not seen overlap of the numbers.
Is there a complete listing of these issues available online, or from
someone on the list? Can anyone confirm
that the numeric part of the catalog number (i.e. without the prefix) are
unique?
Thanks!
Best wishes, Thomas.
