The “large thing” looks like some kind of coil+ferrite core to me.
AFAIK That is really part of the tuned circuit for the radio
reception.

That sounds plausible, although I’m not an electronics expert it has that
look to me. Ideally it would be good to unsolder it and place it on the
other side of the board but that probably won’t be possible. If it was a
coil+ferrite core would extra the length of extension wires effect the
tuning?

That is definatly a tuning coil. You may be able to swap the coil to the
opposite side of the board, but adding long wire would be a vey bad idea. If
you swap it, orientation is very important. You will need to mark it’s
oreintation on the main board and then remove it. While removed, test
continuiety between the wire leads of the coil. If there are 2 pair of
connected leads, you should be fine. Just make sure each pair of leads is
mated to the correct hole pairs. Be careful, these things are easy to
destroy.

I have since unsoldered the battery connections from the board, this allows the
whole thing to be removed from the casing. Having has a look at the other side
of the board I have decided to leave the coil as it and move the two switches to
the other side of the board, as Brian Williams did
here The ‘underneath of the board is
then pretty much flat with only small surface mount ‘thingys’ and a chip.
If I was to move the coil to the other side it would be pretty easy, it has six
pins in two connected sets of three (i.e only two connections) so providing I
marked it as you say then it would be a simple swap.
I’m going to be taking more pictures as I go along and doing a write up when I
finish.
