I'm sure you're aware Elgin had a RR Grade pocket watch line, Named the B W Raymond
Ole B W was the Prez.
I owned 3 pocketwatches during my 39 year career on the RR as Engr.
2 Hamiltons and a B W Raymond. Also owned a 1903 Raymond. Size 18 7 jewels. Non RR
Quite a grab on your part. 17 jeweled. Hope it rocks yer boat Bro.
