Lionel SM-16 Armature - In 1923, Lionel announced a new line of Standard Gauge locomotives powered by their new "Super Motor".  There are basically two classes of these motors. Early Super Motors, (1923-1925) also referred to as large gear Super Motors, have a single compound intermediate gear. These motors used the SM-16 armature.

Later Super Motors, (1926 to the end of Super Motor production) have double compound intermediate gears, with the very first few of them having a manual reverse only. Lionel continued the use of the SM-16 armature in this later motor for a brief period. As Lionel developed its mechanical (or distant) reverse unit and began using it in these motors, they also changed to the SM-92 armature. The SM-16 armature was redesigned and became the SM-92 armature. It featured an improved winding scheme to enhance performance, as well as a reinforced commutator with much thicker retaining rings at the base of the commutator.

This improvement, thicker retaining rings, increased the overall form factor of the armature, preventing the SM-92 from being used in the early single compound intermediate gear Super Motors. The larger reinforcing ring tends to rub against the brush tubes in some of the earlier Super Motors.

Generally these armatures are used is Lionel's Super Motors such as the: 8, 8E, 10, 10E, 33 (Super motor version), 50 (Super motor Version), 318, 318E, 380, 380E, 402 (1924 on), 402E, 408, 408E. If you're not sure which you need, please ask.
