Also on the Title Bar, Moulton Preservation, (founded in 1980), are a great source of parts and services, for F Frames.

Be aware of Brompton front wheels, the hub and axle is too narrow for an F Frame.
Be aware modern 7 and 8 speed hubgears, they are too wide to fit Moulton rear forks unless modifications are undertaken.
Enjoy the restoration of your classic, with alloy components all round and good tyres your Moulton will have a good turn of speed and give many years of service
