Hi all! I'm back and ready to continue learning and repairing!
I tried removing the dial as per Russell & Dave's suggestions. I gave the contacts a wee clean and used a spare strap to short terminals 4&5 on the dial tag-strip.
Unfortunately, the result is the same as when both off-normal contacts are open. That is, if you take the handset off the hook there is a faint white noise coming from the receiver instead of no dial tone at all, and the telephone will not answer a call when the handset is taken off the hook. Instead, a sort of buzz-buzz (as opposed to ring-ring) is heard coming from the receiver.
What's the next port-of-call?

This is a good idea, though I'm guessing if removing the dial completely hasn't resolved the issue then the problem lies elsewhere?
