  • Notes
  • This is the export version of the Ever Ready "Sky Princess"
    The Sky Baby (=BEREC Ballerina) is the same chassis in a small valise style case.

    The Sky Casket (BEREC Harlequin is same chassis) is later but very similar chassis.

    The Sky Baronet (BEREC Matador) is essentially a revised version of similar case and the Point to point wiring with tag strip chassis replaced with a PCB and minor circuit changes

    All use B141 "balanced" compact combo battery packs with 1.5V & 90V to suit the 125mA LT and about 8.5mA HT, probably over 100 hours battery life
