Vintage Wheels spinners

[Troy]

Hi everyone, I'm in need of a quick angle measurement. I'm not even remotely near mine, but need to know the angle of the back of the spinner ear to the horizontal, as shown in the attached picture.

Thanks.

It looks like you are all set up for a simple measurement all ready. Mine are 30deg. as per your drawing.

Thanks Bill, much appreciated.

I had the picture of my adapter on my phone, but am interstate and couldn't measure it.

Thanks for confirming.
