My set arrived today.
If you had told the "boy" Edgar Lecuyer back in 1982 that someday he would be Trainmaster at a railroad and would own an LGB-produced model of that very train set, he would have probably thought you were crazy, but here we are.
As agreed, the locomotive model does include the WW&F history book. It does not appear the production model differs significantly from the prototype pictured in the advertising.
Is it a perfect model of #9 - no, far from it. But it is perfect enough for me (and the boy within, who sometimes still likes to play with trains.)
