• Presumably you know British bikes of that era will almost certainly be made for 27" wheels?
    The advantage is plenty of clearance for wider 700c tyres,but you will need deep drop brakes.
    120 old rear also limits you to 5 speed freewheel.
    Try posting on the CTC website and Retrobike to increase your chances of finding what you want.

    I have posted a couple of bikes to my daughter in Mainz so happy to forward to Germany if the seller is reluctant (many will be, especially on the CTC website)
    PM me if I can help.
    Viel Glück
