As far as I know the AC engined Ace never had a rev counter that went until 60 but always 50. The 60 version was used in the Ace-Bristol. The higher red band would be the original one for the Bristol engine and the lower one added later to make it suitable for the AC engine.
The red paint on the lower red band looks just a little bit less sharp than on the higher one.
This also makes it clear that the CL engine in your car could safely rev a little higher than the earlier UMB version on the left as the red band starts a little higher.
Just my thought. Maybe someone has a better idea.
