Note: The earlier number 946 models, like my model 1,
has different engraving on the back. It is not
stamped 'Motor Barrel' and 'double roller'. My
serial number dates from 1907. The photo shown
must be from a later production.

Curator Response: Thanks for the report. It is just a representation of the grade from original documentation. Markings are expected to vary from era to era during the span of production.
