Is this a CAL 30 or CAL 2 30?

Hi Folks! Can anyone tell me if this is a Cal 30 or a Cal 2- 30 ? Thank you so much !

(the stern has been enlarged, so it doesn’t follow the original design)

The boat is a 2-30, the 30’s had a larger keel shape in the aft I have a 1969 2-30 looks identical to yours.
