This is the Band Switch and the associated "Low Pass" filters.

Each of the six bands has a filter made from a pair of inductors built using the toroids and several capacitors. There are 13 coils and 26 capacitors in total. For the mathematically awake people who realise that doesn't quite add up, one of the bands has three coils rather than two. My fingers are now quite sore from winding all the coils.

I've done a trial fit in the case and have been able to work out where to fit the Tx indicator Led and the enable switch, so some more metal bashing is next on the agenda.
