Repairing 1950s dime store 110v electric bells

[hotrodjohn71]

I found these 'Bells of St. Nicholas ' electric Christmas decoration bells at an antique store and am hoping to get them working to be a occasionally usable novelty gift for my wife.
I have done some testing but still haven't got them to 'ring'.
There are 4 bells, each with a wire wound coil and a plunger inside attached to the bell.
I have tested for 110v AC across the whole setup and it seems ok.
I also sprayed a contact cleaner/lubricant on the plungers.
What would you suggest?
Thank you

Check each coil for continuity with a multimeter. If a coil is open (infinite resistance), it is likely burned out and needs to be rewound or replaced.

Thank you.
The magnet wire on these coils appears to be .005" so im assuming 36awg.
If im not 100% accurate in my count of the number of windings when I remove the old wire and install the new wire with a couple extra windings, will it make any difference in the function of the bells ringing?

No, there's a good margin for error - 10% or more error won't make any difference.
