The part on drawing 12 has gone three weeks without being cast because the mould does not add up. One of the three views is drawn wrong and the draughtsman retired in March.
There is the real part. Turn it, hold it against each view and tell me which one does not match.
Three views of the same part: elevation, plan and side view. They ought to agree with one another like the three faces of a shadow, but one of the three was taken off wrong and that is why the mould comes out crooked. The good part exists: it is here in front of you and you can turn it around.
