NYC MU commuter cars

I need drawings for the NYC's 1950 St. Louis Car Co. lightweight MU cars (originally the 4500-series, later the 1000-series)) and any reference information or narratives on them. Can anyone help or point me in the right direction? Thanks in advance,

There might have been drawings in MR a decade or two ago?

Anybody remember that?

A search of The Model Train Magazine Index http://www.index.mrmag.com/tm.exe turned up one listing:
