Sorry, I've been busy, didn't have much time to tinker. My Vigortronix AC/DC 3W, 3.3V came in yesterday, so I'll get back to this topic soon and post back my findings.
The bell is actually a 3V, and yeah, that's quite rare. It's the Friedland D902. Sounds German, but I think now it's a subsidiary of Honeywell. It's quite loud too, given it's low power specs.

The important stuff to figure out is the bell. So since you say "I will use MOSFET", for now how do you drive it ?
Is the bell really a 3V one ? it look pretty rare. Do you have a picture of the bell, because old ones are usually 12 VAC.
