The #2AA dial alone is worth probably twice or more of what you paid for the whole phone.

Its nice that the switch hook springs weren't used to switch the light on/off.

Look at the 4th picture and you will see that the switch hook does in fact switch the lamp on and off.

Would that have damaged them?

Not sure if the arcing of 120 volts damaged the contacts. The main problem is that since this is a 151AL (anti-sidetone), there should be two sets of contacts, and no continuity between the bottom two (B and Y) and the top two (R and BB); there should have been a phenol insulator/bumper between the two sets of contacts which also forces the top contacts together when going off hook. The lamp maker either removed this insulator or bent the contacts to get continuity between Y and BB.

Not being knowledgeable in electronics, all I can do is take a video of the contacts for you to analyze.  http://youtu.be/RbR6LYYAJA8

OK, now I'm confused because the switch seems to be operating properly. I don't see how the next to bottom contact (Y) is making with top contact (BB), which is a good thing for using as a phone but doesn't explain how the lamp worked....Also, there is a rubber "bumper" missing on the hook itself which would insulate it from the longest (B) contact. You might at least wrap the contact with electrical tape where it touches the hook, or follow previous thread on replacing the bumper.

Is it me, or is there something missing from the transmitter?

It's not you.  It's a diaphragm that's missing.

You're not missing :)

(Sigh).  Ok, parts and work list so far:

Receiver.
Transmitter diaphragm w/screws (or maybe just get an intact transmitter).
Wiring harness.
Repaint.
Dial maintenance.

Perhaps not the entire receiver, just a cap and diaphragm.  Maybe the cord too, not sure if this is fixable, they had the restraint attached to the dial (first picture in second post).
