The decision for which receivers would be used for the U. Carbine Models M1, M1A1, or M2 were made well after the receiver was completed as all of these models used the same receiver.

The Ball Watch Company branded and distributed watches made by Hamilton, Waltham, Illinois, Elgin, E. Watches marked "BALL & Co." are much more difficult to find than those marked "BALL WATCH Co." Ball watches are today some of the most collectible of the American railroad pocket watches. Ball was overseeing over 125,000 miles of rail tracks in U. A., Mexico & Canada, having greatly contributed to the security of all railroad systems.
The Ball Watch Company did not manufacture watches directly, but the company helped develop the specifications for watches used in railroad service.
Webb Ball established strict guidelines for the manufacturing of sturdy, reliable precision timepieces, including resistance to magnetism, reliability of time keeping in 5 positions, isochronism, power reserve, accompanied with record keeping of the reliability of the watch on each regular inspection.
