East London Engineering
I’ve discovered that there’s a 3rd London based Model Engineering Society, out in the East is the “Dockland and East London Model Engineering Society” according to the Model Engineering diary page they are still active, model making and running trains in East London. I’ve not been able to find any contact details and I don’t believe they have an active website.
For the mechanically minded there’s also the East London Inventors Club based at the University of East London. Each month they have talks on topics such as patents, design and funding.
