Research Note: According to Elgin Master Records, some Grade 150 movements were modified from pendant-set to lever-set, changing the official grade to 277. While none are specified in the documentation from this run, #6457145, #6457308, #6457327, and #6457534 have been reported as lever-set. #6457817: Verified as Marked "No. 150" and "21 Jewels" on the Barrel Bridge [eBay #274519965502]. #6457036: Verified as Lever-Set with "Adjusted 5 Positions" and "No. 150" Marked on the barrel bridge (appears that it might be a later addition at the factory as the movement was adapted). #6457602: Verified as Lever-Set [eBay #404286726698].
