Glad Robert Y checked in on this. He is the modest but extremely hardworking Marine and all-round great guy who works as VMB-613 Assn. webmaster. He has been tirelessly helping me research a magazine historical/build article on the PBJ-1. The man knows his PBJ’s.
It was never operated by the Navy, only the Marines, who were bailed 700 of them from the Army. Only one G model was bailed and it wasn’t used except for testing. Otherwise, the Marines flew every variant of the B-25 in combat except the B.
There are references out there, such as Alan Carey’s “Leatherneck Bombers, B-25/PBJ Mitchell Squadrons in WW II” published by Schiffer. Then there’s the Osprey “PBJ Mitchell Units of the Pacific War.” Both have great color profiles and drawings. Be careful using the Squadron Signal “B-25 In Action” and “Walk Around” books. They are great photo references, but like most aviation writers and modelers and war buffs in general, the text has incorrect information about the PBJ, which has been unfairly passed over by historians until just recently. (Both books quite often incorrectly identify the B-25 variants in the photo captions.) The PBJ-1 subtypes were designated by a letter that tells you which B-25 version they originated from, such as PBJ-1C for one that began life as a B-25C and PBJ-1H for a cannon nose B-25H version (cannons were removed and replaced with two or three machine guns in some cases). The PBJ-1J was used by the Marines as well late in the war, both glass- and gun-nose versions. The CAF’s Devil Dog, which I had the good fortune to fly in about 20 years ago, is supposed to be one of the latter, but isn’t a real one. Unfortunately, the paint job is not even very close. The Marines did not permit nose art, and very rarely will you see anything more than bomb mission marks on a PBJ. They wore every scheme that tactical Navy a/c did. The late J models based on Iwo Jima and Okinawa, and using the huge Tiny Tim missile late in the war, were overal FS 15042 Gloss Sea Blue, while a lot of the H models used the three-tone scheme until the end of the war. Most, however, were blue-gray over white for most or all of their war and training time.
The main external difference, besides the color, if you want to make a PBJ-1, is the addition of a radome in either the ventral turret position or over the glass nose, as I wrote in an earlier post, to make the “hose nose” PBJ. They were quite common and butt ugly. The H and J models carried the radome on the starboard wing tip. Also, PBJ’s, which were primarily strafers and low-level bombers with air supremecy, very often did away with the top turret altogether, leaving just the lip.
About six months ago Joe Myers of AcMin told me they are trying to make a PBJ conversion set for their B-25C/D, including a torpedo and other armament. But despite what you may hear or read, no PBJ is ever recorded as having fired a single torpedo in anger. They trained for it, and the instrument panels were wired for it, but by the time they got the the Pacific in Feb. 1944, there were no decent shipping targets left. Still, you will often see the photo of PBJ-1D “Johah” at Cherry Point with a torpedo slung under the open bomb bay doors (it wouldn’t fit inside), but this is a PR photo.
Eduard makes an excellent, three-fret PE set for the Monogram kits, with parts to backdate the old Monogram H, a very good kit, to G standards. It includes parts to add the “bay window” modification to the waist gun positions. Changing the Monogram late-war B-25 to an earlier one such as the B-25 C, D and G models involves moving the forward dorsal turret to the rear of the fuselage, because the H and J models of the B-25/PBJ had the turret even with the wing leading edge, and the earlier models had the turret aft of the trailing edge. On the other hand, all the AcMin B-25 models are early ones, with the aft turret. Eduard makes a B-25 PE set, most of which is appropriate for the C/D and G. It’s a quick way to identify early and late B-25’s, since the noses were so often modified in the field. Most or all PBJ’s had the raised tail gunner’s “greenhouse” position fitted, even the earliest ones.
One more thing in this long screed: the Air Force Museum “B-25B” representing the Doolittle Raiders, and whose cockpit and instrument panel is often used in modeling reference books, is in fact a D model.
