Note: I don't know if this will make it easier or harder
to pin down the grade, but this is the only 18s,
17j Rockford I saw in the PWDB with the balance
cock on the right of the barrel bridge, with this
DMK pattern AND the words "SAFETY PINION" stamped
on the movement between the balance cock and the
barrel bridge. See photo.

Curator Response: Thanks for the report and images. Your movement appears to be consistent with the Grade 935 classification. You are correct that most do not feature the "Safety Pinion" marking.
