I remember a old skool metal double skin bell box with drill tamper and a pendulum fitted inside in case  anyone gave it a whack! :lol:

Why would you want to. A bell is a type of signalling just use more than 1 and better signalling. The bell usnt what deters intruders its the fear of getting caught. If Noone hears the bell Noone will respond etc etc

It's certainly done well for an early 2000s sounder 

 

batteries had failed,

 

metal backplate + inner cover

2 batteries,

2 pizeos

2 circuits boards

plastic lid....

 

would have been an expensive item in its day...
