A fire at the Perkins Bacon Fleet Street premises in March 1857 lead to them relocating to Savoy Street at extremely short notice. Once they resumed printing here, the inks used appear quite different. No longer with the varying orange hues of the pre-fire stamps, now with far more Pale Rose shades. In fact some are so pale as to be difficult to discern any detail! They moved back to Fleet Street on 14th July 1857, by which time the inks in use had become a pretty uniform Rose-red....a far cry from the Pale Rose shades that began this short period. When they restarted printing at Fleet Street, the same shades continued, thus the only way to separate the C9A Rose-reds and the Fleet Street Rose-reds of C10 is with dated examples. Based on the latest research (by Mike Williams), the C9A Rose-reds are seen from dates between 26th June & 24th August 1857.
