I was prompted to make this blog post by Simon Atkinson’s own blog post detailing the history of Master Models and Space Models (see this 2023 blog post). Here are some of the links related to Master Models and Space Models association with Gerry Anderson productions such as Supercar, Fireball XL5, Stingray and Thunderbirds and Joe 90. In 1960 Master Models produced the puppet-scale model of Supercar used in filming the series.
1960 – Supercar – Puppet-scale Model – Just out of the Master Models Workshop.
Note the girder style front canopy support, which was replaced before filming the series.
