Neat shot - I just won it on eBay. Looks like the underwing mounting bracket for the bazooka tubes. More important for me, I think this is the 16th FS (51st FG) - a unit I seen only one other photo of!

Cheers,

I also noticed it. A field mod?
A question: Anyone know how many different P-51s the Maj George Preddy flew? He flew P-40s against the Japanese, and initially a P-47 in the ETO . . . but what about his P-51s? I have seen a painting of his P-51B and a photo of his P-51D-5-NA. Did his -5-NA receive a field 'dorsal fin,' or were there separate 'Cripes A'Mighty?'

Specifically 16th FS or 51st FG in general?

Hi Alan,

Yeah, specifically the 16th FS with Mustangs. There are tons of pix of the 51st, but I've only seen one other image of the 16th's P-51 striped tail markings. I'm not sure why there were so few pix.

I used to manage the USAF's WWII still photo collection and spent a couple of years putting all the pieces back together - there was only one photo there of a 16th P-51.

Cheers,


Dana

An F-6B, the photo graphic version of a P-51A. Often incorrectly listed as an F-6A.

AAF sorted out the confusion created when the first P-51-1-NA was converted to photo recon and often referred to as F-6A. In 1944 the AAF referred to it as F-6, P-51A as F-6A, P-51B as F-6B and P-51C as F-6C.
Other naming conventions existed such as Depot modified P-51B-5 as P-51B-6. In short it was a mess. Bob Bourlier has done yeoman's work in sorting these out but it was chaos in 1943/early 1944

I am afraid the transition of Letters didn't follow. The breakdown is as follows:
- Held back Mustang MkIA by USAAF (after Pearl Harbor) initially became P-51-1 (as well as -2 and a few -3), the again redesignated as F-6A when retro fitted with cameras (however, all retained black stenciling 'P-51-1' under cockpit on left fuselage just forward of cockpit).
- P-51A Mustangs, most were also fitted with cameras were redesignated as F-6B, lettering was again left as
'P-51A' on fuselage.
- P-51B and P-51C fitted with cameras became F-6C
- P-51D fitted with cameras became F-6D
- P-51K fitted with camera became F-6K
Sorry
If the USAAF had 'lettered' the held back RAF Mustang MkIA for the US and redesignated these first Mustnags entering service with an 'A' after P-51 instead of just '-1' it may have prevented much of this discussion. But knowing the history of the USAAC/USAAF I kind of doubt it. I have searched unit websites of WWII USAAF units and have found photos of Allison engined Mustangs 'labeled' P-51B, as one example.

Many variations in field terminology existed. That said here are a few digs from friend Bob Bourlier who has pried the lid from the F-6A, P-51A-11, F-6b and F-6C mess.
Start with the Mission assignments in CBI for 160 recon. Look carefully at the serial numbers. The 43-6xxx P-51B-5 are from contract AC 30479 which originally was the foundation contract for the P-51A. When the P-51A-11 was converted Recon, it was initially designated F-6B s the F-6A was still operational in MTO and CBI. The initial P-51B-1 and -5 were designated F-6C, but even the AAF-MC realized they had a confusing mess when the P-51C was so modified at the same time the first recon Ds were converted.. I will post the MC document explaining the different recon models in the next post after the few P-51-1/F-6A were all gone. From that time all P-51B (-1 through -15) recon versions were designated as F-6B, and all P-51C remained F-6C

And i thought only the Germans messed up there airplane codings. Bloody amateurs compared to this.
 
To continue - The Recon table as defined below was dated mid 1944 but I can't find the preceding page. Note the unusual absence of discussion about P-51A-11 "F6" designation. To help muddy up the waters the AC 30479 contract covered P-51A through 310 ships, continued into P-51B (NA-104) for -5 through -15, then extended to cover NA-106 to build the P-51D. The latter was originally set for 600 P-51D with birdcage canopy/six gun wing - but scaled to two ships, then re-distributed in summer 1943, along with NA-107, into AC 40063 (NA-109 P-51D-5 through -15 NT at Inglewood) and AC 40064 (NA-111 P-51C-10 NT and P-51D/K and P-51D-20NT). All these contracts were let from June 42 to May 1943 and the list ends with P-51C-10 NT and P-51D-5 NA with no mention of P-51D-10 or P-51D-5 NT or P-51K-1 NT which were delivered after August 1944

All pointing to presented difference in which P-51B-5 thru -15 NA as F-6B-1 (noted in comments as "similar to P-51A" but Merlin engine) BUT the earlier P-51B-1 was designated at this time as F-6C-1-NA then follow with P-51C-1 NT as F-6C-1-NT. Clearly some crossover in mid 1944

Continue to the second Table with mixture of MACR/accident reports. Note that in the 'type reported' column for the dates Dec 1943 through early May 1944 that the P-51 was referred as only P-51 in the MACR - not F-6A.

Note beginning in May, the MACR referred to P-51A as P-51A and P-51A-11, then thereafter as F-6A. Sometime in mid to late 1944 the AAF-MC issued a series of documents (including the one that designated all NAA fighters in AAF service to be referred to as Mustangs (including P-51 and A-36). It was this block of docs that finally sorted F-6A=P-51A, F-6B=P-51B, F-6C=P-51C; F-6D=P-51D, F-6K=P-51K.

Bob Bourlier has done an excellent job of research into Recon Mustangs and most of this data is sourced through him.

Thanks drgondog. I am still skeptical. It is food for thought. My two sources are Aircraft of World War II, Amber Books, UK, 2017 and Allison-Engined P-51 Mustang, by Martyn Chorlto, Osprey Ltd, 2012. The British are meticulous in their research, hence the reason we used JANES for combat ship identification.
