Mystery Plane

I’ve run a number of mystery plane contests, with my online friends of the Ground Observer Corps never taking longer than about 20 minutes to identify the plane.  So I thought I’d put up a poser.

What plane did I find here on the bottom of the Pacific Ocean?  There’s an oval defense blister on the side, another blister on top, and a cigar-shaped fuselage.  You can see the remains of an engine nacelle on the wing.  The other diver should give it scale.

What have I found?  The clock is ticking.
