Hi All,

anyone got any pamphlets for old British telephone set D, MkV and a GEC Universal 6/7 line switchboard, serial no 733? The switchboard and phones have been in my garage for a few years and all the gubbins seems to be there so thought it would be nice to see if I could get them working. If no pamphlets then any advice on how to get them working would be much appreciated. I know the phones take a 3 volt battery but not sure what size of battery to use in the switchboard, anyone know?

Pictures of the switchboard below.
