Note: Production total indicates 5913 units. When I
total yearly production between 1899 and 1914 the
total production quantity is 3908. One of these is
incorrect.

Curator Response: Thanks for the report. However, the yearly totals also equal 5,913. Make sure to account for the 5 designated with the 1898 estimated production year as well. It looks like you also may have dropped the 2,000 designated for 1902.
