We have a winner! Shorting the mic contacts produced a dialtone. It turns out the contacts for the transmitter were pushed quite far into the handset, and the transmitter itself was rather grimy. I cleaned it up with some isopropyl alcohol and gently bent the pins outwards. That seems to have fixed everything, especially thanks to Russell noting the cam on the dial needed adjusting.
Thanks to you wonderful lot I now have a fully functioning telephone.
Thank you all so, so much! I can't express how grateful I am that the phone is now working.
