REB

German drawings define critical and non-critical dimensions with the number of digits to the right ot the decimal point. The more digits to the right of the decimal the tighter the tolerance (tolerances are defined either on the drawing or via a standard) I have worked with German drawings for a number of years and have not run into a missing or non-defined feature dimension. Some are tough to find and many times they are feature developments, they are defined someplace on the drawing. I doubt that the Germans would leave any dimension open to the manufacturers discretion. If there is a significant dimensional change in the triggers (outside of print tolerance), then there was also print revision.
