By the way, Pete - the Lionel product appears to be the Loewy car body with oval cab windows - Ideal for a C of G 15-44. I always thought it was the later car body, but Lionel advertisements say otherwise.
Oh, and thanks for the nomenclature on those trucks. I really like the Commonwealth, but don't care for the big Baldwin, since a box car towers over it. I guess it was designed for branch lines with light axle loadings and low clearances. By itself, it is handsome; in front of a freight car it is diminutive.
