Great looking train Jeff, that "River" series 6 Rmt -8 Dup -4Dbm is a particularly interesting car, not in the catalog and I'm not sure if it was offered in the mid-seventies limited run sets of kits they did for the Twin Cities or Olympian cars. Can you verify if it has a metal or wood roof? The mid-seventies Walther's series kits all came with a metal "wrapper" that fit over the roof.
My brother Jim has a set of the River series car sides, he's pretty sure they're Walthers but thinks they may have been custom cut by Walther's instead of a catalog offering (since we can't find any of them in the catalogs we have)
As an FYI and per Jim, the catalog numbers for the Pullman-Standard Olympian sleepers Walthers sold in the seventies are as follows 4897 80' 14 Section Touralux "Mountain" series, 4898 80' 10 Rmte -6 Dbm "Lake" series, 4899 80' 8 Dbm -Lounge Skytop "Creek" series Interestingly the "River" series cars were originally intended for the Pioneer Limited, which further suggests they're custom cut.
Cool stuff, your cars and the A-B-A which I assume are All Nation, all look nicely built and exceptionally well finished, I actually prefer the Armour Yellow scheme over the original Orange-Grey-Maroon as it's the one I remember from my child hood seeing those Hiawathas in Glenview, Northbrook and the Dells.
