"ERIE RESISTORS
A T.R.E. FILM in Kodachrome
"

T.R.E. in the film's title dates it to between November 1940 and 1953. According to Wikipedia:
"The development of radar in the United Kingdom was started by Sir Henry Tizard's Committee for the Scientific Survey of Air Defence in 1935. Experimental work was begun at Orfordness near Ipswich. The research group moved to the nearby Bawdsey Research Station (BRS) in 1936. It moved from there to the University College at Dundee in 1939 as the Air Ministry Research Establishment (AMRE). Then, in May 1940, it moved to Worth Matravers as the Ministry of Aircraft Production Research Establishment (MAPRE). It was established as the central research group for RAF applications of radar. The name was changed to the Telecommunications Research Establishment (TRE) in November 1940."

"Telecommunications Research Establishment (TRE) was the main United Kingdom research and development organization for radio navigation, radar, infra-red detection for heat seeking missiles, and related work for the Royal Air Force (RAF) during World War II and the years that followed. The name was changed to Radar Research Establishment in 1953."
