thanks for all the info had to ask since it stood out so much to me.

to CCF..
I'm one of the geeks that convert serial numbers to their assigned Plate Positions, as required for my serial number charts for rare overprint errors on Natick Test Paper and Web-Press Notes..
Unlike all other published Natick & Web Error Censuses, mine is made with serial number charts that show confirmed error notes along with the serial numbers printed with the same error from the sheet awaiting confirmation..
If you would like to know the exact serial numbers, COPE plate position (upper left), and sheet plate numbers (front lower right) your note came from, with your single note, it would take a little time to chart all 32 subject information..
My Census only requires 16 serial numbers per sheet as COPE trims 32 subject sheets into 16 subject 1/2 sheets prior to the 3rd print Overprinting..
While I haven't updated my Web & Natick census here on CCF, I was able to purchase 2 Web Inverted errors from the A-F Block that are new additions along with a third error note to the Inverted Census (first addition to the census in over a year), and a 41st error for the Natick Census..
