PC: 40' boxcars

[KPMF16@xxxxxxx]

I'd like to build a fairly accurate HO model of a PC 40' boxcar.  I only have 
one picture of one off the Internet and it appears to be PC 350305(?).  It's 
a 40 footer with a 10ft. plug door, or as close as I can tell that's what it 
is.  I don't have the PC Color Book yet, so I don't know if there are any 
good pics in there.
I have an Athearn 40' box but its probably bogus including the number series.
I realize that the PC's boxcar fleet was primarily 50 footers which I have 
found a fair amount of info on, but I thought that at least one sample of the 
smaller cars would be neat.  Can anyone out there help me out?  Thanks in 
advance.
