What if the UK prop store didn't use any Hong Kong radios but a local brand? We have seen this happening already with the Karrimor frames, the toilet syphons, the tupperwares sto&go and few other bits on the backpacks. How many radios they needed? Four, five and few custom ones to mock up the real ones. Maybe buying them in a local store without going that far to buy few would have been simpler. I have seen many re-branded ones or specifically made for the UK market.
