This underframe was designed as a common item for a set of three GNR 4 wheel coaches.
The coaches comprising 1st class and 3rd class saloons and a 3rd class saloon/brake.
The inspiration for these models was a set of coaches produced in OO gauge by Hornby. These coaches are not claimed to be highly accurate to any particular prototype. The object was to produce low cost models that look in keeping with the Aster Stirling Single 1/32nd scale live steam locomotive.
The underframe is my first release. The three body shells will be released to follow during 2025.
