You can re arrange the strips inside the tuner any way you want, I wonder if they sold different knobs or indicators for different areas?

Models with the 'projection knob' (numbered transparencies that would appear lit in the knob center when in front of the dial light) allowed you to replace sections of the transparency with UHF numbers when using UHF strips, so you could probably re-order the transparency and channel strips any way you wanted on those sets....Even make them not match for April Fool's Day.
