N&W pre-1959 depot / tower telephone

[NW Mailing List]

Dear Abram;

please don't apologize for loquaciousness.  You are one of the few sources
for this information, and some of us appreciate the time and effort.  If
someone isn't interested they can use the delete button or just move on to
the next message.  Thanks for your assistance, and your assistance to my
good friend Dr. Frank.  Have a healthy and peaceful Thanksgiving.

Yes; I still hope you'll let the turnips sit for a few days and make it to
a convention.  Cleveland is lovely in June.  (subtle, hunh?)
