Hi Gav! Just joined to ask— do you know the differences in font from the faceplate for the kHz? I've been asking around, but as of yet can't find an answer. Copying my observation from ClassicZCars, as it looks like the radios above have the smoother, more sans serif font:
A more rounded sans serif font, as seen here, here and here (on the $310k BaT sale)
A stenciled, almost "military" style block font, as seen here and here
