somebody knows how much voltage I have to apply to an old telephone bell to make it work?

old phone line ringing was around 75VAC

tho it will probably work from ~ 50 volts onwards

Frequency was dependent on how fast the caller cranked the magneto.!

I worked with telephone systems in Canada in the '80ies. The ringing was 90VAC at 20Hz. The ringer mechanically resonated at the 20Hz and 50Hz or 60Hz probably will not make it work. Other countries used different voltages and frequencies, but since you did not fill in your location then we are guessing what your ringer needs.

We do not know its size so how do you know it was a telephone ringer and not a completely different V and freq fire alarm ringer?

I got the telephone from a friend here is austria.

I know it is a telephone ringer, because I took it out from a telephone :)

Does anybody know the telephone ringer voltage and frequency in Austria?
An old North American telephone had two bell heads and the electromagnet hammer toggled between them. I cannot remember if the frequencies of the two bell heads were different to make a musical chord.
Here is a photo:
