No; that's normal. The stamped end of the tube indicates the long butt
-- where the builder should trim when cutting the tubes. All the main
tubes, fork blades, and steer tube were stamped, but not the seat stays.
753 tubes were *NOT* stamped; the long butt end was indicated by a
swatch of paint.

Actually the gauge of the wall, IIRC.
