I got curious about what the exact differences between the plans and the book drawings were, so I compiled a list showing what is the same and what s different. I have attached it as an Excel spread sheet. I can't guarantee there aren't any errors. Some of the print is hard to read. Both were purchased from Jim Bede in 2000.

NOTE 1: THIS DRAWING IS LISTED
IN THE MASTER LIST AS BD-4-2-04 SHEET 2, BUT THE ACTUAL DRAWING HAS A DIFFERENT
TITLE
NOTE 2: SOME DATES WERE NEAR ILEGABLE AND I MADE THE BEST GUESS THAT
I COULD. ALSO, THE PLACEMENT OF THE MODIFICATION BLOCK VARIED AND IT IS
POSSIBLE THAT I MISSED ONE OR TWO.
NOTE 3: SOME OF THE 1976 DATES MAY BE 1970 DATES. THE ZERO HAS A
LINE EXTENDING ABOVE AND I INTERPERETED IT TO BE A SIX. OTHERS WERE CLEARLY
A SIX.
NOTE 4: DATES ARE DIFFERENT BUT NOTES ON REVISIONS ARE THE SAME.
THE BLUEPRINT (PLANS) LOOKS LIKE THE DATE MAY HAVE BEEN CHANGED FROM 70
TO 76.
NOTE 5: THE DATE WAS ACTUALLY CLEARER IN THE PLANS THAN IN THE BOOK.
THIS IS A THREE SHEET DRAWING, AND THE DATE SHOWN IS THE LATEST DATE ON
ANY OF THE THREE SHEETS
(Ed.: I marked the lines where the book differed from the plans with yellow).
