Red, I think I will hold onto it, but thank you for the offer anyway. [] And yes, the glass seems quite thick to me.

This is a picture of the left side of the logo. Had to mark the beginning of it with my thumb because I couldn't even see it through the view finder.

I don't know if this helps, but this is the thickness of the glass. At least from the top.
