The RAF ( ? ) 101 is a quite famous British airship of its time.. I don't have any of that material with me.

For the Burney automobile, I've not seen any numbers.
There will be numbers for the airship.
Along with the frontal area of the envelope, they'll be:
* frontal area based Cd.
* surface area based Cd
* and volumetric displacement based Cd
