The data sheets you are refering to are unfortunately only available from less than a handful of the old builders.
When the Peterborough Canoe Co closed in 1962 the serial number records were lost or destroyed.
However, your canoe was likely built sometime between 1958 and 1962, judging from a number of construction details visible in the posted photos for example the slat seats and thwart style.
