Thanks guys for all your info.

I have taken some pics and it would appear that one is actually a Plessey from 1942 (as printed on the magneto) and the other is a T.M.C which seems to be a bit newer.

Still struggling to identify why the ringer on the T.M.C is not working. I have an idea from using the multimeter, that it could be capacitor 2 (pictured) that could be at fault or the actual magneto bell, as both the magnetos are giving good voltage readings. I think I may buy a capacitor and see if does the trick.

Dave, thanks for the pics of the buzzer, it would appear that both these sets have the induction coils, so no buzzer for me then! I have also gone for the 4.5v flat batteries and these seem to do the trick.

It would also appear that one of the mics in the Plessey handset is not working very well, it is marked YI/YA 7873 No 9 . In the T.M.C there is a red mic marked YA2308-MK.V, any idea where I might get another one of either of these to replace the duff one?
