Have gotten lucky lately with a few finds, first up:
Bing American Market: Pennsylvania Lines 529 Maroon Observation Car, New York Central Lines 253 Green Passenger Car.
American, UK, and German Markets checked. That’s not even breaking it down, however, between passenger and freight. Canadian is next I guess...
As the literature says, Bing studied Ives before entering the US Market.
Possibly why I get such an Ives feel from these 2 and why they go so well with this Ives 3250.
