Hi L.

In the olden days.... the "plastic" model was built for 3-D, inteference, construction etc, that scale was 1:33 1/3. That is why the GA's were drawn on that scale. Even now it is still used with the CAD models drawings. The scale rules can still be obtained. Although I see them less these days. Not an old hand myself though but above is true.
