I am amazed by how modular it is. Audio amplifier and IF strip on plug-in PCBs. Without desoldering anything you can remove those, the ferrite rod assembly, the frequency changer PCB, etc. It can't have been cheap to make.

Hi Tony, It should also have R. 390 on the dial, in the bottom half of the dial under the red Scotland. It appears to be the same dial as this KB.
