What we have here is a section of a drawing and not the whole drawing (hence the title: "Section AA side view) This drawing is ONLY a view of Section AA and does not contain the full part. When a drawing has a section that is set apart for viewing it will most often be magnified (scaled) for the purposes of clarity but maintain the previous dimensions even though the scale may have changed. The draftsman most likely didn't include additional notes on the scale because it was obvious that this section was scaled for viewing purposes only. No harm done.
Here is an example of a drawing of mine that uses the same magnification technique.
