(Most countries were protectionist to a degree at that time of course, including Britain.)
Those trade 'barriers' could be quite helpful. The Co. I was working with made studio mixers and at the time the only comparable item was from Rupert Neve imported from the UK. Since we were making a comparable item, we managed to get a 20% import duty on the Neve stuff!
The only thing that got my goat in Australia was the fact that (in theory) I was not allowed to do house wiring although I was considered competent to design and install a 3Ph power supply for a TV transmitter. I got over the wiring regs when we moved to the bush and having my own generator, was deemed to be the electricity 'authority'!
