The Masterline commercial models were carried over after the discontinuation of the Master. In 1957 the light van was lightly changed and was now fully glazed, rather than having pressed steel in the rear side windows. The first generation Masterlines were built until replaced by a new Crown-based generation in March 1959, for the Toyota Store sales channel. A total of 19,400 Master and Masterlines (excluding the Central Motors-built RR19s) were built by Kanto Auto Works until production ended in 1959. A smaller Coronaline version was also developed to be sold through Toyopet dealers.
