Does the fact that the sheets from which these coils were made had variable spacing between adjacent stamps? Some spacing was 2 mm and some was 3 mm. Just a thought which may be totally irrelevant to the problem at hand.
Not irrelevant at all. In thinking how those perf machines were set up and how the operated, I don't understand how I would have been confused in the first place, that one stamp might be a smidgen wider than the one next to it.
