Remarks by Robert Bracken: "The 430 Squadron Mk.XIV only carries its individual letter code - as 430 at the time did not display its unit code, for some reason."
11/15/2006. Remarks by Antoni Lachetta: "430 Squadron was a tactical reconnaissance squadron. It was normal for tactical reconnaissance squadrons not to display the squadron codes. This dates back to the days when Mustang I's were used for this role. Pilots were concerned that the sky coloured codes made them too easily recognised when approaching the target. As a result, from May 1943, the squadron codes were painted out. This is why so many Mustang I's show only the individual letter."
