Yes I remember, early Valve radios had huge screening cans, with a Small I.F tranny in the middle, to get a good Q
The Navy loading coil housings, I mentioned above, were Huge, about the size of a "Brick built s/house" for same reason
On the Mi-Amigo, in it's former life as "Radio Nord" off Scandinavia, it too had similar huge "tuning boxes" on deck
Not for a feedpoint Loading coil, but each contained, a coil and vacuum capacitor, to bring each of the lower ends
of the folded umbrella drop wires to resonance, at the Low end of the MW band
Mast Base was grounded to deck, with the shunt feed wire, going up well spaced from mast, right to the top

Scroll down a bit, you can see the 3 tuning boxes on the Left of the colour picture, (zoom in, same colour as hull)

Captain insisted on someone going out on deck, to check for Seagulls perched on antenna, after one went flash/ bang,
when TX was switched on, as all they found left, were a few feathers
When Radio Nord closed, and Mi-Amigo became Atlanta/ Caroline, the "tuning boxes" were scrapped,
and Freq. shifted to 1.6meg end 199m etc
