Movement Markings: Republic

Curator Response: Thanks for the report. As far as I know, the Grade 35 was always described with a safety pinion. The movements in the 4,000,000+ blocks do not have safety pinions, so our closest grade classification is the "Century." "Republic U.S.A." was a private label.
