I was quoting the T.F.. I find those old Periscope Films fascinating. The German radar would lock onto a target and send a firing solution to the FlAK battery, but with computation, loading, traversing, and shell travel to 5 NMs of altitude, a 20 degree change in course from what was anticipated would send the shells relatively harmlessly off to the port or starboard, then moving back to the primary course would repeat the process.

"$295.00, This Airspeed Indicator is a WWII-era US Army Air Force Type D-7, Bendix Pioneer PN 1426-4T-A10-1, as used across a number of US Army Air Corps and Air Force aircraft during WWII, including heavy bombers B-17 and B-24, medium bombers B-25 and B-26, as well as light bomber A-20, according to the Maintenance Interchangeability Chart dated Dec 1943. It was also used in versions of US Army Air Force WWII fighters P-38, P-39, P-40, P-47, and P-51."
Although I have read about A-20s and P-39s meant for the Soviets, but diverted to the Pacific. Those read in meters and KMPH.
