The plain version, as you put it underwent a number of changes throughout its run. Intoduced in 1970, it used a BNC-60AH nosecone which changed to the injection molded nosecone soon after. I've yet to pin down that date. The injection molded nosecone shipped in white, and IIRC also in black (however my photos were lost with the HD dump back in September). Later K-52Ps and the 1200 shipped with blow molded PNC-60AH motors and were 2mm longer than the previous version.

The K-52P also underwent changes in the recommended motors over time. In 1970 and 71 they used the D13-0/D13-7 motors for payloads up to 5 oz. and D13-0/D13-5 motors for payloads over 5 oz (D13-5 motors for single stage). In 1972, and for the rest of the production of the OMEGA, the recommended motors were D12-0/D12-7 motors for payloads up to 5 oz, and D12-0/D12-5 motors for payloads over 5 oz (D12-5 motors for single stage).


Presumably, the K-52 (which you called the Cineroc Launch Vehicle (shortened as CLV)) also changed motor recommendations in 1972. However, my instructions are older than that, and I've yet to seen newer instructions.
