Data in the "Size" column is essentially as it appears in the original handwritten records with the exception that parentheses have been added to indicate that the data contained within only applies to part of the group. Where movements were adjusted, the adjusters name sometimes appears in the records. The abbreviation “Adj” has been added within the "Size" column to indicate adjustment to "heat & cold", or to "heat, cold and position" as originally recorded. In other records this has been detailed in the "Notes" column.
Grade indications are absent in the earliest numbers. Later grades are indicated by price, and still later grade numbers were provided in the records.
Abbreviations used:
" * " - Potential additional data to be added at a later date
