Hi Bruce, thank you for your reply. There are a few Cal 9.2 around here, build in Brazil in the 80s. But this one is not a Cal 9.2, but a Cal 30. Different model, and build in California.
Here is where I found the info : http://www.mostsailboats.org/1967-jensen-marine-cal-30-2/
I wonder if this information is accurate.
