The planning progressed in the same manner with the G series. Continuous innovations, a new type mark was published aggregating these then. For example, the late G-6 and early G-14 the same type. G-14/AS and early G-10 have minor differences too. It occurred that later types received previous type components because of production or supply difficulties. In the later section of the war this increasingly more considerable.
