The Pattern is actually 1951 and not 1952 as many seem to call it and it was a hybrid pattern which used pieces and adaptations from both the 1937 Pattern Web and US Web. The Canteen, Canteen Cup and Carrier were adopted from US designs and manufactured in Canada. The Canteen Cup and Carrier were interchangeable with US models and as time progressed US manufactured examples were issued similtaneously with Canadian pieces. 1951 Pattern Web was initially issued to the final Korean rotations in 1954 as well as the Canadian Infantry Brigade in Germany starting in the mid-1950s. Full sets of the pattern were not available when the web set was initially issued and it was not uncommon to wear a combination of 1937 and 1951 Patterns until the required pieces (namely the Canteen and Cup combinations) were available for issue. The 1951 Pattern remained in use by the Regular Force until the mid to late-1960s when it was replaced by the 1964 Pattern; and many Reserve units until the early 1980s when the 1982 Pattern was issued.
Here are some Canteen, Cup and Carrier images from my collection.
