Question about knog. Blinder 1300

Yes

Go Pro plate screw no idea if it was included.

Well, mine didn't come with one and I've just looked on the packaging and there's no matching screw listed, just the mount for the lamp on the GoPro plate. The screw is included with every GoPro mounting plate anyway, so it's logical that the screw is not included with the Blinder 1300, see also the description on the knog homepage: https://www.knog.com/products...
