I do know that Dayton Legal Blank had the contract for the whole state of Ohio for ballots. They would probably be your definitive answer on the precinct numbers.
The punch card I used was yellow, folded over and the write in candidate went on the back of the fold over. I believe the write in portion is torn off and then the punch card is tabulated by a tabulator at a central location.

If you visit
http://cardamation.com you will se there are card readers, card sorters and card punchs. If tabulation fraud has occured I do believe they can replicate the cards they would need to match the output by programming a card punch to create punched cards. These cards would have no fingerprints and likely would differ from stylus punched cards.
