This model number was used twice previously - firstly for the smallest of the Mayflowers, in production 1928-31, for which there is no example available on site, and then for the second smallest of the Ultra Moderns, in production 1935-40, which may be seen in pictures 86 and 87 in Volume 2. In 1970-71, the No 50 was apparently being produced by both Lines Bros and Walter Lines' company Good Wood Toys, which he founded after retiring from Tri-ang. Manufacture in 1972, was by the Barclay Toy Group/Barclay Securities Ltd, who had bought the rights to the Tri-ang trademark, after Lines Bros had gone into liquidation in 1971. The Barclay Toy Group was itself sold in 1973. There is no evidence that the No 50 was still in production at that time. The house shown is probably an example of the very earliest version of the model, dating to c1948/49: it is Marion Osborne's opinion that dark grey roofs appeared on the first of these houses. These early models were sold with wooden bushes in tubs flanking the front door. These appear to have been lost in the house seen here. A photo of the interior of this house is not available on site. Apart from some very minor details, the layout remained the same throughout this model's long production run. Please see picture 4, subsequently, for a view of the interior of another early No 50 interior.
