Hi,

Researching on some ships, a series of Ardrossan built ships for Coast Lines Limited. They all had Campell Isherwood swichboards, (1936-1949) but i can't find any thing about them (unless they are in a technical instruction book).

Switchboards would of been 220 v DC and supplied either from shore supply/ 3 auxillary generators.

I do know that they would of been made at Liverpool...

If anyone has any ideas or pointers please reply
