Research Note: Factory ledgers designate this run as Grade "PSB" (P.S. Barlett). However, #1025260 (the last movement in a block of 60) has been verified as marked "Appleton, Tracy & Co." The runs recorded between 1025001 and 1025400 switch multiple times between 10-Size P.S. Bartlett movements and 10-Size Appleton, Tracy & Co. movements and have similar features.
