PC: PC MP-54s

["Gene Chase" <echase@xxxxxxxxxxxxxxx>]

Looking for color pictures of Penn Central MP-54s.  I have one of the MP-54
at the Pennsylvania Railroad Museum at Strasburg, PA. Does anyone know
where I can get a roster of re-painted MP-54s from the PRR era?  Were the
same numbers kept?  I have seen the MP-54 picture, March 10, 1976, called
"Final Roost" that was in Trains Magazine. Only 2 head-ends have the PC
emblem?  Have also seen article in Trains, Jul' 82, "The Dim Cars." 
I assume some MP-54s were not re-painted but retired?  Thanks,
