I found a set of glass in wall of building being remodeled; how can I find out what it came off of? All pieces flat, scoop bottom top loop windshield I have found on lots of cars at car shows, back 16 1/4x14 3/4 and 4 side windows 17x22 1/2; the windshield measures about 42 " wide. House owned by rural farmer probably "plain jane" car; Model A Club says not a Model A. Are there books with published glass charts from old cars? Thanks, Grace in AK gratron at yahoo dot com.
