Thanks for the reference. You know, I'm a member of TCI, but I have
no idea how to get into any of their online stuff. (Every time I try
I can't get in). I get their paper edition of the newsletter and
that's it.

NYC started off with 3L+5D, but soon switched to 2L+6D since they were
running out of exchanges. I think when they switched the dial pulls
stayed the same, that is, PEN- became PE 6-. In contrast, when
Philadelphia had to switch for the same reason (after WW II), they
dial pulls became different for almost every exchange. (ie WAL became
WA 2, WAV became WA 4, and some exchanges completed renamed.)
As an aside, to this day, in the Philadephia official exchange charts,
the original name still is used for the address code, that is, you
will see "WAV" for everything in the WAverly district.

I just found out that they existed in Cinncinati in the 1931 panel
conversion of Cherry Parkway. If the party letter was missing or
wrong on a dialed call to a manual exchange, a signal would light for
special operator attention.
Thanks again for the info.
