Research Note: Elgin factory serial lists designate 375,001-376,000 as grade "F.R." (Frances Rubie), later including it in the Grade 23 number classification. However, only one 10-Size Frances Rubie movement has been verified from this run, #375010. The remainder of the run is comprised of various experimental, prototype, and special order movements. For this reason, the run has been split in the database to segment the original Frances Rubie production from the experimental and special order movements.

#375028 and #375030: Verified as having features consistent with the 16-Size Model 4 Grade 83.
#375031: Verified as 16-Size Model 4 "Chronograph" featuring a unique timer mechanism added to movement [Heritage Auctions].
#375074: Verified as 6-Size Movement with 3 Finger Bridge [IHC185].
