Are the layouts of these standard, meaning would the layouts of say a Hurricane Merlin data plate be the same as one for a Whirlwind Peregrine?
Once again theres only the one photo of the Whirlwinds data plate...
I've enlarged it by 200% and enhanced it see here both a positive/negative image.
Can anyone tell me are these standard data plates issued by Roll-Royce?
I've already tried R-R Derby and they say they haven't any information for the plates used in the Whirlwind...
