I don't have examples as bad as that, but I had some WTF moments while working on a 1937 CCM. It was actually pretty well made, but the mass-producing techniques were evident. The lugs were tack-welded, and the mitres were very crude (almost excusable for the one-piece headtube). The seat lug was very nice with sharp transitions, the ST and DT were 1-1/16 OD.
