Hello all,  I have recently picked up a 27" Regina music box and
am looking for a 27" Regina discography and disc repair article:

1. Does anybody know of a discography of 27" Regina discs I could
get -- book or on-line?

2. I have an opportunity to pick up some discs for it that need
projection straightening.  Does anybody know of an article -- book or
on-line -- providing guidance on how to do that safely and accurately?

Didn't find much of anything on either via Google.
