Plating a sheet of the 30cMRC

By sheer luck, this second sheet is from the other plate of 100. The previous incomplete sheet showed a 5 by 5 or half sheet symmetry. This one shows a column by column symmetry. With these two sheets I have plated 189 of the 200 positions in the early plate. Here are corner scans.

The overprint shows almost no variation. The only break I find is to position 7.
