A bit more info:
"The Typhoon FR IB was developed in early 1944 and was used as a tactical reconnaissance fighter. In this version the port inner cannon was removed and three F.24 (one forward facing 14 inch and two vertical five inch) cameras were carried in its place. Later, when it was found that the recoil of the two cannon on the starboard wing was not properly balanced by the single cannon to port, causing a yaw during firing, the starboard inner cannon was also removed from some aircraft. Because of the inherent airframe vibration the photographs produced were usually sub-standard. After some service with 268 Squadron from July 1944, the FR IB was phased out in January 1945."
So I was wrong about just the one camera. Please see attached images, not too clear, I will try and clean them up. This is another aircraft I will have to add to my site.
