There are a few items in the index/calendar to the collection that were not filmed: items 747, 1238, 1312,  1573, 1758, and 1843.  

There are two items in the index/calendar that the film scanner skipped/missed:  items 573 and 1573.

There is one item that is not  in the index/calendar but exists on film:  item 1301

There is a skip in index/calendar numbers that  do not appear on the film and probably are item numbering mistakes, meaning that they were not used to sequence and film the collection:  items 1491-1493, 1834, and 1861.
