Honeycomb Grids and identification of angle.

[FlyTVR]

I bought some grids years ago. I picked one up today and pondered. How do I know what degree it is. It doesn't have any markings.......

Apologies if this is a dumb question.

Do you really need to know?
If you do, fit it to a flash, put it some distance from your camera, pointing directly at it. Take a shot.
You will have lens flare. Now move it progressively sideways, taking a shot each time, until the flare has just about disappeared.
Then measure the angle
