Craig, Thanks for sharing. These photos show an example how the VMB squadrons were able to adapt and modify their PBJs for the mission(s) at hand.
In regards to the disposal of their PBJs after the war, the following story of VMB-611's MB 4 shares the feeling of the flight crews upon their return to Pearl Harbor.
On November 8, VMB-611 circled Ewa Marine Air Base, coming in to line up along the apron. They were met by jeeps with MP marked on their sides. Pink-cheeked guards in freshly starched khakis climbed out to station themselves around the bombers.
"What the hell is this," growled one veteran as he climbed down out of MB 4 in faded dungarees. The Sergeant of the Guard turned and replied "These planes are going into the ocean."
There was stunned silence. The veteran's teeth went through his cigar stub. He turned to look at old MB 4, faithful, hard-flying MB 4. A lump came up in his throat. He had flown in MB 4 from Page Field. He had been with her during the trip to Espiritu Santo, over Kavieng and Rabaul, into the Philippines, and to China. From there he had flown with her all the way across the Pacific Ocean to Ewa. Now they were going to dump her like a piece of junk into the ocean. An unreasoning rage began to climb up the back of his neck.
His buddy saw it and grabbed his arm. "Easy, pal," he said. "There is nothing we can do about it." The veteran shook off his buddy and slowly walked over to the plane. He touched its side. Then it hit him. It was over. His war was over. He would go home now.
