Did you ever find it difficult to find this very thin style of glass used in the small windows of dust covers and 400-500 etc. models?
Well it is very cheap to buy this 1/2 strength glass.. Go your local 99¢ store or dollar general store or whatever you have in your area.
There they sell the cheapo picture frames, which have this very thin glass in them..throw away the frame and you have the glass often available in 10 x 14". cut all your own glass in quantities..very simple
