The graph border on these scans are to help with getting the proper size.  The grap is divided by small squares that are a 10th of an inch in size.  The darker lines are at the half inch mark.  So, ten lines make up an inch in distance.  I hope this helps.  Let me know if you have any problems or any special requests.  I will try and help you out if I can.  Merthyn1@yahoo.com
