Please see the caption to picture 2, previously, for the history of the model number. The house shown here dates to 1959-62. It can be dated specifically to within three years by the absence of a front doorstep. A photo of the interior of this house has not been included in this Album. Apart from some very minor details, the layout remained the same throughout this model's long production run. Please see picture 8, subsequently, for a view of a typical No 50 interior.
