Some columns came from the old websites without part numbers. Nothing is missing because of this, and every link works.
If none of the parts of a column had a number, they are listed in the order we found them. The numbers down the left of the list are just the list counting one, two, three. They are not part numbers from the column itself.
If only some parts had a number, the numbered parts come first, in order. The parts without a number come after them, with a dash where the number would be.
