Keep in mind that the D12s were introduced in 1972. The blow molded PNC-60AH was released after 1975. The all numeric catalog numbers first appeared for all the existing K-kits is the 1975 catalog. It took a bit of time to change the face cards depending on how well a particular kit sold. Some of the instructions changed faster than others. Even today, the production runs of Estes kits are not very large.
