I have searched the groups already to see if any previous posts could
help me with my problem, but most either point to sites that no longer
exist or contain snarky remarks. So let me start by stating, up front:

1. I am aware of what year it is. It is 2007.
2. I own a cell phone and subscribe to DSL. I also have a satellite
dish. My cars have EFI, not a carburetor. So I am not behind the
times regarding technology.
3. Not that I owe the sarcastic among us an explanation, ibut/i I
am ichoosing/i to augment my touchtone phones with a rotary phone
because iI/i think it's cool. I really don't care what iyou/i
think, so keep your caustic, derisive comments to yourself.

Okay, with those unpleasantries behind us, let's begin!

I just picked up a wall-mounted Western Electric rotary phone. When I
went to plug it in, I discovered that, while there is a jack on the
bottom for the handset cord, there isn't one for the line into the
wall.

There is a rounded opening beside the the jack through which nothing
protrudes, and I cannot discern its purpose. Through it I can see a
portion of the left-hand ringer bell. On the back, there is, one-
third the way down, centered horizontally, an oval opening whose
purpose I also cannot discern. Through it I can see the wires that
leave the dial assembly, and gear teeth related to the dial mechanism
are also visible further back. All the wires here are connected to
things except for two yellow wires which were either cut or are spare.

Now, removing the cover, the phone is laid out thusly: At the top, of
course, is the chrome, metal hang-up bar. Below it is the dial
assembly. Below this, on the left, is a black, rectangular wiring
block marked NET 425B. On its side is stamped "C NET 425B," then a
column of ovals marked, top to bottom, "GN," "B," and "R." Beside
that is a group of markings with "F" and "A" in circles; then "RR" and
"K" in circles; then an oval that says "G" and a circle containing
"L1;" and finally an oval containing "L2." Then, in the middle, it
says "8-58." This is clearly a diagram of the wiring block, though I
have no idea what these letters stand for. Beside the wiring block to
the right is a tape-wrapped electrical coil that almost certainly
powers the ringer. The bells are below these, the low-tone beneath
the wiring block and the high-tone beneath the coil. Stamped on the
inside of the phone's backing plate are the numbers "554BMP," and
there's a white sticker that says "8-75." (Is this a manufacture
date? That'd be cool to know, because it would mean that the phone is
three months older than I am.)

So! I need some kind soul to help me figure out what I'm looking at
here so that I can wire this antique into my home line. There's
nothing fancy with the home wiring; I have a single line with DSL
filters installed. If someone could just tell me how to get a line
out of this phone I'd sure appreciate it.

Do I just splice red and green wires from a phone line into the
switchblock? Both the red and green wires from the handset jack are
screwed into the same place on the wiring block--is that right? Are
those two yellow wires coming from the dial assembly extra, or were
they cut for some reason? Was this thing wired to be a prop phone on
a stage someplace before it came to me?

Thanks in advance.
