This is a most interesting thread - I do get what everyone is saying but the harsh realities of the manufacturing process involved with producing RTR models is that I cannot see any mass production moving back to the UK.
To make it economically possible you need to run machines at least 5 days a week 24 hours a day.
The labour rates for anything to do with plastic moulding is sky high - 1 good toolmaker will cost you £35,000 a year, a mould technician will cost you about the same. If you are running 24 hours a day you need 3 of each...
The number of models produced would need to be massive, my belief is that Dapol are making more items like the wagons or other low labour items.
Sadly we do have a massive skills shortage in the UK for plastic moulding these days - I spent 16 years in a mould shop working in a factory that employed over 500 people as a trade moulder that also did tampo printing etc. the factory went bust 14 years ago. The toolroom had nearly 20 guys at its prime and we had a get together over Christmas - we have all moved on to other industries and the key thing is that all of us to a man said as much as we found the job interesting we would never go back to it as it was so tough to do and other industries paid more for less stress!
