Wooo you probably have a rebadged Carlton by Alec Bird.Capella lugs were used on Carlton;s from 1959-65 approximately and featured on their Catalina and Clubman frames which were plain guage tourers and also found their way on to some Raleigh TI's presumably to use up a batch of lugs.However it was possible to have a choice of lugs as well and you could upgrage your top of the range Flyer road or Flyer or Madison Track with the ornate Capella or even more ornate International lugs.The Flyer was then replaced in road form by the Pro but continued in Track form until both were replaced by the Raleigh TI Pro series. .
