John: The NASG wheel and track standards were adopted in 1981 and after that Don Thompson went on a personal mission to inform new and existing manufacturers. Only the earliest S scale brass was gauged to the older NMRA standards. The Alco Models RS3, Overland's SD40-2, a PBL(?) standard gauge Shay and Sunset's Big Boy are the only ones that come to mind.
Most of those manufacturers either exited S scale for other reasons or made the transition to the NASG wheel standards quickly. I suppose somebody will take me to task on this, but I am not aware of any brass S scale models produced to the (by then) obsolete NMRA standards after 1985.
