Kevin McElhone did, in fact, produce a list of 15-1/2-inch Regina
tunes, which is already included in the MMD Gallery.  The list carries
the note,

 'To be read in conjunction with "The Disc Musical Box Handbook" by
  Graham Webb as this list only includes titles missing from the book.'

The list also appears on the web site of the Musical Box Society of
Great Britain.

Kevin produced the original lists when he was Archivist for MBSGB, and
has since handed over the management of those lists to me.  I sent an
update to MMD a couple of years ago, which, I think, is the one in the
gallery.  I would be most grateful to receive any additional lists, or
updates to existing lists, so I can update the masters (although I am
currently a little behind on updating them).
