Thank you Dave and Dags

It's all working! I cleaned up the connections and tightened screws, checked the capsules, and now it works just fine. Using 2 x AA on each phone.
It's a non-buzzer type.
Just need to find a couple of spares now. I'll post in the wanted section.

As to restoring some more:
Would you polish the bells? Or would that destroy the aged look? Do people care?

Thanks for all your help on this, my first visit to this forum.

Regards,
Ben
