Oh sorry Collin, I messed up a bit. The 1d,5d,6d,2s and 5s were printed by Waterlow as I am sure you know better than me. They are the only ones printed with the line perf, while all others were printed with comb (Bradbury and De La Rue). I heard some of the later Waterlow were done with comb, but never seen any. I do know the Elizabethan issue have comb and line, for those values changed to cents.
My ancient Commonwealth Five Reigns seems
to suggest that the last De La Rue printings of the 3d (black & deep blue, 27/4/55) and the 1/- (black & deep turquoise-blue, 8/5/51) were comb perf 12.
