Serial Number 2570043 was reported as inaccurate.

Note: It’s a 3 finger bridge watch and was considered
a railroad grade watch at the time.. This one is
in a JS Lewis Co, Ogden 88 loaner case.
Curator Response: Thanks for the report. If the movement is only adjusted to three positions, as indicated, it would not have qualified for railroad service at the time.
