I recently purchased a small group of ½d postage dues from 1932, watermarked 'CofA', perf 11 x 11. These are the ninth series of bi-colour dues, SG D105, Scott J57, ACSC (3rd ed 2020) D113.
Two frame plates were used in the printing of the green frames. FP1 was the only one used on the CofA ½d value.
The stamp at top left of the left pane is position FP1. It features a spur on the 'I' of 'AUSTRALIA' and is seen from the earliest printings on this frame plate from 1909.
The stamps shown are from the later use of the plate in the mid 1930s. The left three show the 'normal' state of the flaw, the fourth stamp shows a deterioration with the 'L' and 'I' of 'AUSTRALIA' joined.
