This boat is not a CAL. The smallest model in the CAL
line was the CAL 20, built from 1962-1975. If this boat is called a "Cal" it would be a very different Cal brand, not to be confused with the boats built in the USA orginally by JENSEN MARINE, Later by CAL Boats, and finally by CAL/O'DAY. Most (well ,all but 5 models) were designed by C. William Lapworth. The 5 'non-Lapworth" designs were the CAL 22, CAL 28-2, CAL 33-2, and CAL 39-4, all by C.Raymond Hunt Associates, and hte CAL 9.2 which was a Rob Perry Design. Some of the Lapworth CALs were also built under license by CALGAN Yachts in Canada.
I'll include a CAL 20 picture.
