The air speed indicators were quite similar but differed in the speed range. Below there are two ones Mk IXE and Mk IXF of the Ref 6A/ calibrated in MPH but not in Knots. Certailny the Ref numbers were different as well.

Mk IXE fitted to early Spitfires and all Lancasters.


Mk IXF fitted to later Spitfires
