I have a 4-tube suitcase portable Rees-Mace "Gnome" which appears to have a similar circuit to the "5-tube" Rees Mace schematics shown here. 

It features a built-in cone speaker and loop antenna in the hinged lid.

The first tube is a screen-grid RF amplifier (Mullard PM12M) followed by a triode grid-leak detector and two triode audio amplifier stages (PM2HL & 210HL, if I recall correctly).  All are 2 Volt British "accumulator" types.

As found, it had three Burgess 45 Volt "B" batteries dated 1934 and an unmarked "C" battery with several unusual female "banana" plug sockets so the bias voltage(s) could be selected.  The accumulator (storage battery) was not with the set when I found it, so I don't know what it looked like or how it was connected.

It has two bands: long and medium-wave.

The March 1939 issue of "Radio News" magazine shows a curious boy at the beach looking into the guts of one of these sets.

 

Attached is a photo of this set.  I have several more photos which I can upload soon as I figure out how to get this model added to the Rees-Mace list on the museum site.
