KGVI Plate Number Question

Afternoon all, today I found a GB KGVI 1941/2 definitive with a combination of control number and plate number that is not shown in my very old edition (1980) of the KEVII - KGVI GB specialised catalogue. As you can see, it has control T46 and plate number 210, but my catalogue only shows plate 210 used with control U47. T46 uses plates 201 to 205. Does anyone have any more recent info for this control / plate combination? Thanks in advance.
Best regards

The 'plate' number, commonly, is referred to as a cylinder number for these photogravure stamps.
The Sg Specialised, Vol 2, 12th edition (July 2005) corrected the listing. Cylinder 210, only, is known with control T46.

Probably, in the 1980 edition, an error was made and someone just started assigning U47 to all cylinders in the range 209-220, when 210 was used earlier during the accounting period T46.

Yes, I should have written 'cylinder', silly mistake. Thought it was the catalogue at fault here, would have been amazed if it was a new discovery! Thanks NSK.
