The center image is of the same section of an unpopulated board from my second run of replica's.   I attempted to make a very few minor improvements in accuracy for this run.  These tiny changes were not worth the effort and added the great risk of introducing new differences between the replica and the original.  Futher improvements will not be attempted, if more boards are built in the future.

The area between rows A and B was particularly difficult to replicate: replica on left, rev0 number 1.299 on right
