"Also noticeable in Canada within the first year of war's end was the renewed
emphasis on the actual manufacturing of 16mm projectors. The Ottawa-based
Northern Tool & Gauge Co. Ltd., for instance, from February to September 1946,
manufactured about one thousand 16mm projectors, about half of which were sold to
schools, churches and hospitals throughout the country, with the remainder exported
to South American and European countries, such as Argentina and Portugal, with
additional distributors established in Africa and China. The portable projector came
in an aluminum case, was approved by the Canadian Standards Association and life
tests proved its durability for over 3,000 hours. The Audio Visual Educator, as it was
known, retailed at $585 in 1946 (roughly $7,100 today) but was available to tax exempt
organizations for $430 ($5,200). It was the only noteworthy 16mm projector
manufactured in Canada at the time and was actively promoted, and demand was
known to exceed supply. By 1948, for instance, the principal distribution outlet in
Montreal was a full six months behind in supplying new machines to customers. By
that year it was estimated that 6,000 16mm projectors were in use in Canada, many of
which were the product of Northern Tool & Gauge Co."
