[Boatanchors] Marconi Magnetic Detector.

[arc5 at ix.netcom.com]

Anybody know someone or a group who can relate specific
details about the Marconi Magnetic Detector?  Google returns
general outlines.

Specifically, I need detail on the insolated iron wires which pass through the detector coil.  Were they a single wire, wound through-and-through several times,, or were they single wires making a bundle, somehow connected end-to-end or was each a single "turn" looped back on itself, or...  Know anyone who has specific knowledge about it?

Thanks, guys.
