I never noticed it mentioned on the instruction sheets of certain AMT kits, but there it is, on at least five early AMT kits:
Was it realistically possible to assemble each of these kits without any glue, and not have some of the parts fall off? AMT might have been using the term "assemble" lightly, similar to what some of us would do in a test fitting stage, and the 1932 Ford Roadster does appear to have rather large locating pin holes in the of the cowl for the windshield frame:
Maybe the tolerances were just that tight from the get-go?
