The caption reads as follows:

Experimental armament installation. The Thunderbolt flown by Colonel Fred Gray of the 78th Fighter Group had two20 mm cannon manufactured by Oldsmobile mounted under the wings of this aircraft. It was thought that the added punch of the two cannon would be a real plus in strafing missions but the installation did not prove to be successful. The cannon added considerable drag and knocked top speed down by 50 mph. Streamlined fairings had been designed but were not installed when this photograph was taken on 24 October 1944. It was hard to beat the destructive power of the standard eight .50 caliber guns and the aircraft was converted back to standard configuration. The aircraft was at Duxford, England when the photograph was taken. (USAF/72320)

Good question! Since Oldsmobile didn't design armaments it was probably licensed... but from whom?

I figured out it is most likely an AN/M2 20mm, which is a license built HS404 20mm.

No doubt that only two cannons won't have the firepower of eight .50's.

And about the speed drop, just think what the speed drop would be if those eight .50's would be mounted on the outside like those cannons. http://forums.ubi.com/images/smilies/88.gif

Of course now that we have found one operational example of this configuration we should pester Oleg until external 20mm cannons are made a loadout option for all of the P-47Ds.
