Here are some Spiegel pages with dates -
speigel-99-relatedThe majority of Speigel's won't letter because there are no log entries for the serial range.
Might be because they're logged as Sp
iegel's and not as Sp
eigel's - take note Roy.
PS, it took me awhile to remember just how it was spelled, probabaly still some old posts of mine out there with it wrong. I see Rick (from WI) had it right, even put it in quotes.
