GPO/BT Bell type 56

[Drek]

I recently acquired an old telephone bell Type 56 probably circa 1960s but it is a Type 56D ( stamped onto the base).

I see many type 56C Bells on the web but can find no information at all about this one.

Can anyone help please with infor re working voltages etc.

thanks

56D doesn't appear to be listed here:

http://www.britishtelephones.com/bell56.htm

are there any coil impedances or voltages marked on the coils?

I am grateful for the assistance of memebrs and I am also greateful to another interested p[arty for provding the following information: -

Bell 56D - 2-5 or 5-10 volts DC (2 x 50 ohm coils) - includes Bobbin Resistance 2k ohms.

Which is just the information I was looking for,
Kind regards to all.
