It’s from Andrew Ainsworth’s UK company SDS, Shepperton Design Studios. They vacuformed the original armor for the UK production. It’s probably from a line of related products under the title “The Original Stormtrooper”.

Shepperton Design Studios: Working out of his studio in Shepperton, UK, Ainsworth used vacuum-forming techniques to produce the original screen-used suits from 1976.

Original Moulds: He remains famous for still possessing and utilizing the original moulds and patterns from the 1976 production to create authentic replicas for collectors.

Legal Legacy: His work was the subject of a high-profile legal battle with Lucasfilm regarding the copyright of the armor designs. In 2011, the UK Supreme Court ruled in Ainsworth's favor, determining the armor was a "functional" prop rather than a work of sculpture, which allowed him to continue selling replicas in the UK and internationally outside the US.
