The cylinder?? Look as if it's wrapped with wire like an oscillator coil
& has a lid on top. _JD_ TIA



If the lamps are ballast resistances, the cylinder may be an
electrolytic rectifier

For charging or perhaps HT though possibly not big enough for the latter

Sorry guys! You are looking at part of early long wave wireless receiving setup, With the tall vertical tuning coil and below a magnetic detector to hear morse transmissions before crystal detectors then valves finally became the norm. Transmitter not in picure, would be spark transmitter with induction coil and spark gap. FOXTROT 310
