A guy posted this on R-e-d-d-i-t saying it belongs to his father who raced it in England back in the 60s. The father now wants to restore it by having the frame chromed. No indication as to who made the frame, but the lugwork looks very nice.
Apparently I can't link to the original thread because of the bikeforums filter. Not sure what they've got against R-e-d-d-i-t.
