That's a B-24. The Pic is small so its hard to make out details. That might be a mod center. Consolidated (the B-24 manufacturer) had a plant in San Diego, but I don't know if they built B-24s there.
Shape of the tailplane says B-24Joe, are you sure with Liberator? I'd say this aircraft is smaller, B-25 maybe?
