Thanks for the info. One point if you are looking at accuracy....
Given your 1960s timeline the Centurion would be a Mk.5 and not a Mk.3....the purchased Mk.3s were quickly converted to the Mk.5s in the early 1950s.
The 1/72 scale kit would be appropriate for a Centurion Mk.5 from the LdSH(RC), 'C' Squadron, 4 Troop stationed at Canadian Forces Base Calgary up to 1965. In 1965 the Strathconas rotated to Germany until 1969 and used the Mk.11LRs.
