In an idle moment while I'm rained off from other vital activities I've put the two pictures together.
They are indeed remarkably similar.
So, a few quick comments:-
The white blob on the right of mine is a 'Portable Aerial'.
It's quite heavy and in a Metal Case under the Label. It measures 14.35 uF on my Gadget. I suspect it's full of Snake Oil.
It connected in Series with a small Variable C at top Right which I suspect is an Aerial Trimmer, and then to the Coil.
The two Main Tuning Capacitors are pretty obvious.
There are two Switches - Long/Medium? - below them.
The Variable C at the far Left is the Reaction I guess.
The Detector Section has a Trimmer/Bandspread Capacitor just to the left of the Screen.
It shouldn't be too difficult to work out the Circuit when time permits.
