I did wonder how much attention the designers had paid to end-user ergonomics, both with that original co-axial tuning knob arrangement (more suited to one of those big pre-war Marconi domestic sets in a comfortable middle-class 'drawing room....) and a distinctly un-stealthy and night-vision-destroying tuning scale design. The BC348 arrangement with narrow-sector, masked and dimly-lit white-on-black looks far better suited.

The later tuning knob/drive set-up may be bulky and obtrusive-looking, but gives the set a purposeful edge.
