ISTR that Telefunken kept up the many-gangs tight front-end theme post-war with double-tuned bandpass arrangements between RF stages, not sure how many gangs this involved in various models.

The larger tuning condenser connects to LW, MW and the 40-100m band and the smaller one to the two other shortwave bands via the wavechange switch. Nothing very exotic.
And the custom made gears do look like they were made in a motorbike shop.
