Well done on a successful restoration of such a complex radio Gabriel - it sounds great on the video!
Thankfully, the Ekco service data is comprehensive and runs to 12 pages.
The circuit looks quite daunting, with a high component count:
Ten 9-way switch wafers. (Your bandswitch picture looked so scary I had to view it from behind the sofa!
24 inductors.
8 bands.
11 valves, (including the DM70 magic eye).
70 resistors.
91 capacitors.
With its two 10" speakers, push-pull output stage, noise limiter, bandspread tuning, it must have been a really expensive radio in its day. From the diagram, the stringing of the dial looks quite complex so you did really well with that, including 3-D printing of the cursor assembly.
I see that it was fully tropicalised and wonder if that had any influence on their decision to use permeability tuning (evocative of car radios)? Probably not. With a pair of EL42s in push pull, it seems that they too often featured in car radios, as referred to in post #7 by forum member 'synchrodyne' in this thread:

There was a forum thread in 2010 by someone in Oz who had an A182:

Being an export model, the A182 must be a rarity in the UK.
Here's a thought as to how it might have found its way back here:
Brought back to Britain from Australia by a returning 'Ten-Pound Pom' who didn't settle there, (as many didn't)?
The 'assisted passage scheme' attracted some 1.5 million migrants from the UK between 1945 and 1972, but 250,000 came back. (If they didn't stay 2 years, not only did they have to pay the fare back to the UK, they also had to pay the full fare for their journey out there). Adult migrants were charged only ten pounds for the fare, thus the colloquial nickname 'Ten Pound Poms'. Only a fraction of the full fare, but it wasn’t a trifling sum. Ten pounds in 1945 when adjusted for inflation amounts to equivalent to £475 in 2022. (Children travelled free of charge).
The scheme was created in Australia in 1945 as part of their "Populate or Perish" policy to substantially increase the population and supply workers for the country's booming industries. In return for subsidising the cost of travel to Australia, the Government promised jobs, affordable housing, and a better life. But migrants were housed in basic migration hostels, job opportunities weren't always readily available, and not everyone 'put out the welcome mat'.
Obviously off topic for further discussion but the link below is well worth a look - particularly the video, which says much about prevailing attitudes of that era, both in the UK and 'down under':
