WTB: Circuit/Manual for "l.f. receiver"

[Nigel Holmes 03 9626 1914 fax 03 9626 1917]

        I've got a non-working Selective Voltmeter model 2174B made by
        Rycom Instruments (Railway Communications Inc., Raytown, MO)

        Has 11 miniature tubes, looks late '50s vintage.

        It looks like it could work as an l.f. rx from 0 - 420 kc
        (AM/LSB/USB, 50c/3kc/10kc xtal filters etc)

        Any information would be appreciated, especially a circuit or a
        manual.
