PFE R-40-1 or A.R.A. 1924 Reefer diagram?

[SandyEggoJake]

So I've been burning up Google w/o luck in hopes to find a copy of a diagram of the PFE R-40-1 built by Pacific Car and Foundry (ACF) in 1927, based on the ARA 1924 Refrigerator Car design.  Not sure, but I'm guessing that the ARA might have been published its original drawing in the ARA proceedings of that year, but I've yet to locate.   

Any suggestions where I might find either?

  do You have the BIG PFE Book ?
  would start there.
  then do a google of magazine conversion articles.
  if Westerfield made these as a Kit,Get One !!
  the Instructions will have the Car History besides
  the assembly instructions.

Thanks Spikre.  All good suggestions. 

By "Big PFE Book", I assume you mean Pacific Fruit Express by Tony Thompson, et al, 2nd edition?  Yep.  First stop.  It doesn't have the C-40-1 diagram, but notes what I'm looking for is CS diagram 4200.  I already got the  builder pics directly from the CSRM, but they claim they didn't have these diagrams in their PFE collection.  I did find some diagrams of some components (really little more than fairly illegible photocopies) in "Pacific Fruit Express #1B" by Da Costa. 

But I hoping to locate the source docs, or even just tips on where else to look. 

Best I can tell, I don't think Westerfield ever made made this one, but Sunshine did and I already have their instructions for thier kit already.
